Well, that's true if the cylinder isn't firing because of an electrical problem, but not if the misfire is being caused by a dead injector.
For a cylinder to fire you need a spark, fuel, and compression. If it has those it will fire, and all are easy to check.
You need to find someone who isn't guessing but knows what he's doing.
Unlikely, but it could be the one wire from the coil to the cap. Could also be the rotor arm or the cap itself. Finally, just because it was replaced last summer doesn't mean the coil can't be bad.
I took it to local shop (not Dodge dealer), they hooked up their computer to look for some diagnostic code, but there was no code, so nothing could be diagnosed, at least at this time...
I thought she might have been up against a curb, which would make it difficult to turn the wheel, but she was in the middle of the parking lot, and that would not explain why dash lights would come on...
Has anyone experienced this situation, and could you resolve it???...she is obviously quite afraid that it might happen again...thanks...
96 SLT Laramie 5.9 automatic with 200k mi. on it.
Does not like to shift into reverse or what feels like 3rd gear. Going forward it revs to about 3500 almost right away once I put it in gear and give it gas, then stays around 3500 while going 30-40 mph, but I never feel a shift once I get to that point (never kicks down), so I don't try to go any faster (it used to get up to 70 mph faster than I could believe). When I try to shift into reverse, it often does nothing at all regardless of how may times I try to shift, turn the truck off/on, etc. On the times it does shift into reverse, it does so with a big kind of 'clunk' and then jumps into gear. I have noticed that it takes longer to get to this relatively usable condition when the weather is cold.
What are the things that I should be looking for? Is this something that I can do myself (with 200k, I don't want to spend too much)?
I have a new '06 3500 with the Cummins 5.9HO 610 Diesel. In the past, I have here and there done my own oil changes on my gasoline engines, partly due to costs, but just as often for convenience.
In regard to this new diesel truck, would you. A. Recommend strongly that I have the dealer do the oil changes out of warranty concerns and get used to the cost. B. Make sure I use Mopar oil filters and recommend I use ???? brand oil, making sure I ??? (such as fill the new filter with oil to protect my turbo), or C. maybe another option like a lube/oil specialty shop?
Also, it LOOKS like changing the fuel filter is a straight forward job by a drop in cartridge in the housing that I can drain water from the filter at. True?
And last but not least. Is a 5000 mile (nice, round, easy to remember) oil change interval a good one, or wasteful by far? I tow 2-3 times a year for < 100 miles each time.
Thanks.
I also put an OBD-II scaner on it and pulled these codes:
P0740 Torque Converter Clutch Circuit Malfuction
P0783 3-4 Shift Malfunction
P0306 Cylinder 6 Misfire Detected
I doubt that the misfire has anything to do with it, but 740 & 783 definitely do. Does a 740 code mean it could be an electronic problem that does not require cracking the transmission open for? And is it indicative of a common, specific error when 740 and 783 are found together?
This is only a cold weather issue. In summer, starts up with no problem. As it get colder, the time it takes for the relays to begin clicking and finally finish clicking so I can start gets increasingly longer. I have waited up to 1hr for clicking to start and have had clicking last for more than 10 minutes before it stops.
It also does not matter weather engine is hot or cold. On cold days, I can turn engine off hot and 5 minutes later, it will not start till it goes through the clicking motion.
i have already replaced the relays themselves with no change.
so does anyone have any idea why this is happening any clue at all would be helpful as this vehicle is my work vehicle and it has to carry me around the midwest HELP!

Make sure also that any ABS/speed sensor in the axle housing is compatible with what you have at the moment.
Finally, as you've a 4x4, it's critically important that the new axle has the same final drive ratio as your old one.

A 'manufacturer's code' is a non-standard OBDII code and so cannot be identified by a generic OBDII reader.
Any code is there to notify you of a problem.........the code itself isn't the problem. Resetting the computer to remove the code doesn't fix anything, as you've found out. You have to fix the problem that caused the code, then do a reset to remove it.
You need to have the code read by a dealership, or an independent shop that's a Dodge specialist.

FYI - I knew that the kid at AutoZone was a moron but was willing to try anything because I am trying to sell this truck and don't want to sink a bunch of money into it first. I should have traded it in a week ago when I was at the dealer (and the truck was still trouble free) but I thought I could do better.
Go to a dealership and ask what the codes are.
“An occasional problem on this vehicle is the failure of the Condenser Fan Motor (4.7 VIN N and 5.9L VIN Z engines only). This problem may cause the Check Engine Light to illuminate.” This came off of autos.msn.com vehicle ratings page.
I have had trouble with my AC the last few warm days that we have had. When the engine is idling the vent blows warm moist air, so I am thinking that I need a new compressor. My question is could the failure of the condenser fan motor or the compressor cause the P1491 code. :confuse:
Thanks for the help.
Why assume the worst? It could just be low refrigerant.
I have already checked the refrigerant and it is fine. Only at first was I assuming that the compressor was going. Then the check engine light came on with a P1491 code (Rad Fan Control Relay Circuit) and I was wondering if that could case the AC too work only during normal driving. There was also the quote about the condenser fan motor, and I was wondering if that would also cause a P1491 code.
As you may have noticed, we are reorganizing the Forums to allow better focus and easier searching when you have a particular problem or comment about any given vehicle. Many of the large generic discussions (like this one) will be closed to new posts, and we ask that you continue in the more focused discussions that you can find at the Group page for the vehicle, linked below. This discussion will not be deleted, so you can still search for information in it.
We recognize this is going to take some getting used to (for the hosts too!), so please bear with us. If you have any questions, you can always email the host of any discussion - the link is at the top of each page to the host who oversees that discussion.
If you don't see a discussion in the group appropriate to your question or comment, start a new one, or send me an email, and I'll point you in the right direction!
Thanks!
