PS Glad that the Dakota regular and club cab owners finally are finally being recognized.
liter V-8 in January 2000. The vehicle is a great
truck in every respect except one, gas mileage.
About the best I've been able to get, unloaded and
on the freeway at 65mph is 16.4 mpg. Since I have
two friends with Chevy, Z-71, 4x4 pickups with
larger engines that get better gas mileage I'm
somewhat perplexed. The Chevy's weigh more than the Dakota and they have a larger engine. About the only thing I can come up with is the gear ratio in differential match up with the engine torque. To my knowledge Dakota only has two options for differential gearing, 3.58 or 3.9?, mine has a 3.58.I believe th Chevy's have a 3.47. Anyway I'm wondering if anyone else is experiencing a similar disappointment or has any suggestions to improve the mileage. Getting a Chevy is not an option as I really like this truck.
I have some questions regarding the Mopar seat covers. The parts dept could not determine what the catalog meant by "3 Piece". They do not seem to have separate numbers for bucket and split-bench. Do the same covers fit both? From past posts I had the impression that the seats were different widths. I ordered a set but I'M not sure they will fit.
Here's a good question maybe someone can help with: how large is the gas tank supposed to be? When my low gas indicator turns on and I fill it, I put about 16 1/2 gallons in. If I run it down to empty, I put a little over 18 gallons in. I was under the impression the 4wd Dakota came with a 22 gallon tank, but this doesn't seem to be the case. Anyone know what the deal is? Thanks.
the road mileage. My trips to the New Jersey shore
yield around 20 MPG (relatively flat terrain, cruise control and few stops). How many miles are logged on your odometer? Maybe it will improve.

Tonneau covers make about a 9% reduction in drag - I have posted the scientific study a few times in various topics. As previously noted the affect of drag in city driving is reduced. 11 mph is lousy - I have a 2000 Club 4.7 and have never been that low. Most of my driving is highway, but whenever the traffic is snarled (have you ever seen the 401!!!) there is similarity with city driving, and I have never seen anything below about 14 - I do drive stick and I am sure that helps.
Filling the tank is always a problem on pick ups because the tank is mounted on the centre line below the bed and so there is a long straight fill tube that slopes down to it. Pumps cutting out is often caused by the gas swirling around in the tube and hitting the cut out sensor. The location of the vent on the Dakota doesn't help any. My Canadian capacity is 82 litres, I have in fact put more than that in on one occasion.
The 4.7 is designed to run on 87 octane. One fo the main design requirements for this engine was that it would run on regular gas, and there is no advantage to running higher octanes. In high mileage engines there may eventually be a need to go to 89, but I doubt any Dakotas are there yet.
As for the gas tank, if it gets capped off at 18 gallons, but has room for a few gallons more, why does the fuel gauge register full? Assuming a 22 gallon tank, the fuel gauge should be at about 80% full after the pump cuts out at 18. I wish this made more sense.
The ECM is bascially a small computer that controls various elements of your engine's operation. The Technical Service Bulletin that was issued authorizes the dealer to upgrade the software in the computer to correct some defects. This is known as a flash upgrade. It is possible that your bad fuel economy is caused by this software problem and the upgrade will help.
As far as gas gauges are concerned there is a lot of confusion. The standard guage (or gage for my southern neighbours (neighbors)) of any manufacturer will always read above full when the tank is full to the brim. If the needle is directly on the full mark it means 'pretty full tank but you can get more in if you want'. Why do they do this - I have no idea. Incidentally the same thing happens at the other end of the guage - but take my word for it, don't try it!!!

Quad Sport and SLT as having 24 gallon tanks while
all other models are relegated to the 22 gallon tank. This is for 2001 models. Sorry for the error, as I trusted the information supplied by my brochure.

Any comments on the use of Mobil 1 and which viscosity of lil is best for the 4.7L down here in South Florida???
Oh, and this is in Phoenix where summer temps averaged 110+ this year. Winter is almost upon us and the temps will soon be PLUNGING into the 70's.

When selecting reverse it will intermittently act like it is in neutral. We have been back to the dealership 6 times - they can not duplicate. They have replaced the shift cable and module. Has anybody else experienced this problem?
Nothing to worry about, it's perfectly normal.

I have also looked for a good Dodge web site to ask questions and technical advice, opinions, etc. The best site I have found is www.moparchat.com This site is clearly the best in quality, with over 60,000 posts! Good luck either way Trevor!
The second thought, is that I experienced that type of noise with my 1995 Dakota Club Cab. It turned out to be an airstream noise that was generated by the rear slider. When coasting, it was much more apparent. The top mounted handle on my A.R.E. LSII tonneau made a whooshing sound as well, when the rear slider was open. Hope this helps.

I know that straight cut gears in a race tranny will whine simply because they do. Rear axle gears should be quiet. Noise = wear

I can relate to your concerns about the engine seeming to not decellerate as you command it. As you surmise, it is related to the ECM turning off the injectors at what seems odd times. I find going very slow in 1st gear (standard xmission) to be virtually impossible to perform smoothly. The throttle pedal is almost like an ON/OFF switch under those condiditons.
As for engine compression during decel...
The 4.7L engine will not not have the decel... compression that the ol' 318 it replaced had. The valve overlap and timings as defined by the cam profile is very different on the 4.7L V8 hemi.
Just a thought.....
gauge set to be on the "safe" side of empty. On some vehicle I have owned were reading empty, the fill came out around 4.5 to 5 gallons shy of maximum capacity. Of course now, the fuel light comes on at about 1/8 tank of fuel remaining. There is usually some margin.
