You could assume that more air=more dirt, but is there a level of unnecessary restriction on a standard filter?
K&N says that a layer of dirt helps their filter. What would that layer do to a standard filter?
I asked a friend (mechanic) about it, and he had the same concerns, but seemed more confident due to the oil coating on the filter.
I guess it comes down to where you do most of your driving.
Until they can get a workable site with a 'sane' name, find a 'better' air filter than K-N, conform (fully) to SJ specs - like the rest of the synthoils, at least in their test results - and can convince me of their 'superiority' both scientifically and 'long-term real world other wise,' I'll keep using K & N filters and Mobil 1 or Royal Purple (aka as the 'best' synthoil on the planet). Sounds a bit like 'pushy' marketing to me. I've never had anything but positive comments (until now) about Amsoil, BUT this type of pot-shot at a 'known' quality product & silly tree-hugging-name crap is what keeps me from buying products like that in the first place. I drive a truck not a tree, and cars and boats and motorcycles; BTW - I'm a state certified environmentalist and hydrologist (and a petroleum geologist by trade). 'Guard-our-earth?' Get real.
Or believe 'Earth in the Balance' without question like the rest of the lemmings. NOT!
Other than those little details, everything's just hunky-dory, but I did have a REALLY bad day. :-(

Some of the other issues that were listed I don't believe were heritary in nature, and represent single-one off problems. These should have been resolved by the dealer the first time.
It's funny how different people think of quality in different ways. I work with a fellow that has has numerically almost the same amount of problems as the both of you combined, yet he has no problem with the over 40 visits to the dealer. And, he's committed to buying another GM truck. This seems to be irrespective of his experience.

Allen-
my tack fluctuates 100 rpm. Is this normal?
Just looking for some of the expert advice that is
available on this forum before I talk to the dealer.
TIA

How many miles on your rig?
Are you moving or sitting still?
The 4.7L has to 'learn' your driving habits and environmental conditions. (Especially the idle-while-rolling conditions) Experience is that it takes up to 4000 miles for this to settle-out.

I visited some relatives this weekend who lived 200 miles away. The problem started when I stopped at a station and the door locks went crazy! They started going up and down and making clicking noises like it was trying to lock again after it was already locked. they finally stopped and I resumed my jaunt. As I was driving down the road they started doing the same thing! It seems they just get a mind of there own once in a while.
today I stopped for gas and it locked the door after I shut it! good thing I took my keys out.
2000 Quad Cab 4.7 auto with keyless entry and factory alarm system.Anybody else experience this problem? This is the first problem I have had in the first 9000 miles. I got my best mileage this trip 19.1 mpg but, that was no one but me and no load. 65 to 70 most of the way.
Dealer replaced the computer module (~$300) and the problem stopped. The doors had done this several times intermittently over a few years. Once while I was pulling into an amusement park. For a minute or two the locks just had a big party. Stopped just as suddenly as it started. Really erie feeling.
Please post the fix since you are not the first to report this problem.
they will check it out on friday so, I will keep you posted on what they find. This problem continued for the 2 days of my trip and the weather was perfect so I believe it must be a computer or an electrical short of some kind.
Maybe Jack, a.k.a (themacguy) can remember.

The copper excels in pulling the heat away from the center-electrode and sending it into the metal threads where it can be dissipated into the aluminum head of the engine. (The aluminum head is ALSO a good thermal conductor and aids in heat-dissapation.)
Some plugs also have a platinum center electrode which is VERY impervious to '"wear". (Platinum is a relatively inert material) thus it can me made much smaller than a 'standard' center-electrode which promotes a more localized spark.
HOWEVER
I believe you are mistaken about the BOB. (From Memory) I believe it states that the 4.7V8 has copper side-electrodes on the spark plugs. And warns about pre-ignition if these are not used.
Why all this copper? (Besides, GOLD is a better conductor!)
The intent is to keep the tip of the spark plugs 'cool' enough to keep them from igniting the FA mixture prematurely (pre-ignition).
The 'risk' of making the plug tips too 'cool' would cause a build-up of combustion by-products on them during warm-up/idle conditions.
Bottom line:
Keep the plug tips within a specific heat-range to burn off the crud but also not cause pre-ignition.
I will post the details on spark-plug design only if pressed... I do not want to go beyond the scope of this forum.
"Caution: The 4.7L V-8 engine is equipped with copper core ground electrode type spark plugs. They must be replaced with the same type/number spark plug as the original. If another spark plug is substituted, preignition will result."
I believe this is what I paraphrased in the previous message.
Your investigation is correct in that they are 0.47mF capacitors. The electrical diagram calls these out but in reality the connectors are missing from the wiring harness. (although the capacitors themselves are installed on the engine.)
Basically, any capacitance added between +12v supply to the injectors and engine ground will help eliminate voltage spikes caused by the impedance of the injector coils. (Basic analog electronics circuit design when driving coils with a digital signal.)
The intent is NOT to affect a radio. Instead the intent is to protect the ECU (Engine Control Unit or COMPUTER) from voltage spikes (over 100volts) due to the impedance of the coils within the injectors. Another benefit would be to improve the instantaneous current delivery that the injector coils theoretically will draw each time they are actuated.
Why are they not connected on the 2000 Dakota?
I haven't got a clue... but I surmise that that the capacitors are 'installed' when the engine is assembled but the wiring harness does not have the connectors because the vendor that builds the harness does not install the connectors.
It would be interesting to peek under the hood of a JEEP GRAND CHEROKEE which is where the 4.7L V8 made its debut. The BOB for the Dakota was obviously copied from the JGC. (4.7L sections) Perhaps this would point to an answer.
Is there any harm in disconnecting the negative post only and leaving the positive connected, or is it better to disconnect both?
Thanks.
The main drawback I can think of about disconnecting the battery on your Dakota is that the onboard computer(s) will loose there volatile memory. This means that some of the 'learned' settings will be lost. This is the main reason that the system was designed to have the removable fuse that does not affect the computer memory.
A better choice would be to procure a "battery maintainer" that plugs into a 125v outlet and will keep the battery at peak condition for many months if needed. These are basically a "wall wart" plug with a quick-disconnect pigtail that stays on your truck once it it installed. These devices are around 20$ (US) and actually "monitor" the battery to eliminate overcharging.
Disconnecting either or both of the battery connectors will suitably isolate the battery from any draining effects.
For SAFETY reasons, some say it is considerd better to disconect the earth, ground, negitive (-) terminal first. Conversly, the (-) should be connected last when hooking back up.
I am compelled to remind you of the very explosive hydrogen gas that a battery normally produces. (Remember the hindenburg blimp!) Watch out for sparks!!
PLEASE wear eye protection.
It is self regulating and only charges if the battery needs it otherwise, it is in a standby/storage mode. They cost about $50-60 if my memory serves me correct, an excellent thing to have around for many purposes.
OK enough of my campaign speech!
Of course you are correct... this should be extended to say all moving parts should be lubed regularly. This includes doors, tailgate, hood (hinges and latch in all cases.)
I had to replace the 'pins-n-bushings' in the door hinges of my first 2 cars before I learned keep them lubed. White-Lithium grease is waterproof and easy to spray into the nooks/crannies. (but can be a bit messy)
It is not a question of quantity but more a function of regularly being the key here.
Too much grease will just get all over the place with no lubricating benefits in the right places.
A good dealer will lube these items at every oil change. (That is why they call it a LOF...Lube Oil and Filter)
Took it in yesterday. They aligned the bumper and the hood and now everything is equal. Looks much better. Just a product of sloppy final fit and finish at the factory.
I canvassed 3 dealerships in my area and got quotes from $164-$202 when asking for the wheels by part number and $500-$560 when asking for the wheels for a Dakota R/T. The dealers/counter persons can set there own price for parts. Apparently when asking for the wheel by name the wheel is considered an OEM replacement item and when asking by part number the wheel is considered and after-market item, thus the big difference in price. Do not order by name and be prepared for a back order (There warehouse(s) can't keep up with the demand).
Earl
not idle. It runs fine except that it quits
when you let off the gas. I think there is an
idle sensor and I think that's the problem. Has
anyone replaced these? If so, what's a ballpark
on the sensor and where is it located?
Thanks.
iowabigguy--The price DOES include the center caps.
By the way, the parts people were surprised that I had the part number (I got from the Dakota Mailing List).

A 'quickie' way to search the DML topics is using the search ability built into your browser.
A more advanced method is to use a robot or 'worm' that crawls thru all of the appends and builds a searchable database for you on your computer.(The download and database build may take 'hours' but then ALL of the data is available to search without being online thereafter) ... Basic data management stuff... Free software tools are available online to do this kind of stuff.
I hope this explanation makes sense to you...
I believe that the DML uses an ORACLE database as their front-end. There may be an 'online' way to perform database queries against the data. (Sorry for being long-winded but I make my living doing this computer 'stuff' )
Allen-
I had it to the dealer once already for an entire day. Nothing found, "technician" checked suspension, body mounts etc and didn't find anything. Tomorrow it's going back as supposedly, two of the "body noise experts" would be back in the shop as they were on vacation last week.
I've been under the truck myself checking, pulling, pushing and pounding in different areas but cannot duplicate the noise. Grrrr.
It seems to be getting louder or I'm more annoyed by it the longer I need to listen to it. One of the emails from the the DML I received tonight mentioned a TSB on cab/body mounts from '97 up.
Anyone on here ever hear of that or can confirm the TSB so I can share that with my dealer?
Thanks,

I had originally told the manager that I felt it was something suspension related like the torsion bars.
Well, guess what, that's what it was. Apparently, the torsion bar on the right (passenger) side was not seated all the way forward in the lower a-arm. This caused the bar to bottom out on ever little bump and with the slightest twist on the frame.
Rides quiet now. Thanks everyone for the input. It was appreciated even though it turned out to be something unrelated to the body.

The only moving 'parts' are the pedal and pushrod directly into the clutch master cylinder.(Under the hood directly opposite the clutch pedal) Your pedal force is converted to pressure in a pipe from there. At the other end of the pipe is a lever deep within the transmission bellhousing that activates the clutch.
There is supposed to be a dab of grease on both ends of the pushrod. (Hydraulic-safe of course.) If the pushrod was 'rubbing' on the rubber boot, a squeek could be produced.
Unless you are comfortable working around hydraulic components, you may want to have your friendly, neighborhood warrantee shop look at it.
