I've got an 05 Dakota Laramie 4x4 Quad cab and the past week the engine has shut off a number of times when coming to a stop. It seems that the idle speed gets too low when coming to a stop. Has anyone had this problem? If so, is something I can do or do I need to take it in for warranty work?

 

Warranty work, I had the same porblem too it to the dealer and had my PCM re-flashed with new software upgrades. It's a flaw with the software that was origonally put during production, they usually provide the upgrade the first time it's in.......... Check with your dealer.

 

My 06 Raider does this and Mitsu has no software upgread. Do you have a TSB or something that talks about this. I have had my PCM, Cam Sensor, and Crank sensor replacedand nothing fixed it.

 

I believe the PCM programming is the same for both so the Dodge reflash might work for you if you can get them to do it.

 

I called the dealership shop, this afternoon,and theysaid that it is "probably" the spark plugs since I didn't change them out at 30K. I've got 35K on the truck now. The rep had stated that since "Check Engine Light" didn't come on that it was probably a maintenance thing. I've had many vehiclesand I've never changed the spark splugs and they ran "Great" with over 100K. And they where Dodge.

Today, after I talked withdealership, I had mytruck in the driveway, in park, and it wasidleing at 750 rpmsand thenit woulddrop down to 400rpms. It kept cycling like this for about 20mins until Iturned it off.

To me it doesn't sound like"Spark plugs".

I've got an appt. on Monday, Oct. 1st. to have them look at this but any info would be great!!!!

 

Could always try changing the plugs, they don't cost much. My integra took a set of plugs every 10-15k or it would start running like total crap (MSD ignition ate the plugs a lot faster)

 

your idle port on the throttle body may be dirty and the idle motor may be trying to get the air flow correct but cant, thus the surging. You can clean these very easy by removing the plastic intake baffle that runs between your air cleaner and throttle body. Then using basic carb cleaner, start the motor and lightly spray the idle port( located on the lower right of the throttle body). I've done this with a previous dak but at higher millage(70K) and it fixed it. worth a try.

 

I'm pretty sure I saw a thread a few weeks ago about this same problem. The solution: go to the dealer and have the PCM reflashed. Problem solved.

I forget where the thread is and I'm too busy to look, but it should be here somewhere.

 

New plugs did not fix mine. Anyone have info on the PCM reprogram. Mitsu has not heard of it. A TSB # or something I can tell them. I sure a Dodge dealer would charge me to do it, if they do it at all.

 

Mine is doing it still as well. Had taken it to the dealership several times over the past year with stalling issues, every time they would tell me they didn't pull any codes or find anything wrong. Out of nowhere at my last oil change they come to me and say my TB is dirty and needs $174 cleaning and that was causing my stalling. I said isn't this covered under warranty and they said no it is caused by water in the gas. I have used the same BP gas station by my house for the past 7 years and never had a problem with any vehicle and I've had around 6 different ones in that time. I ended up cleaning it out myself and it was filthy but even after cleaning it the truck still idles like it has a big cam in it. Kind of embarrassing when the wife's minivan idles smoother than a V8. If anyone finds anything out let me know as well. I'm sick of this!
