Has the valve timing been checked? This engine has three timing chains and a very specific procedure for setting the timing. I'm assuming the engine came with heads, cams, and timing chains installed, but builders can make mistakes.

Posted on May 20, 2017

Testimonial: "the timing has not been checked as far as i know, the truck runs fine besides the stumble, in fact i can start it up, run it for about 30 secs..shut off and re-start and there is no stumble..runs perfect. guess pcm resets. its a bank 2 failure to go into closed loop" thats the real problem i believe, with new 02, ect i'm really expecting to find a pinched wire somewhere as bank 2 never acheives closed loop. thx old marine for the reply!"

I have a 2008 dodge dakota and it has a very rough idle. It runs great at higher rpm and really rough at idle what could it be and how would I diagnose the problem?


Search google for IAC - Idle Air Control motor. Specify Dakota and your engine size ( ex. Dakota 4.7 IAC ). The Dakota shares some engines with Jeep so you can search for Jeep also. Also search for TPS - Throttle Position Switch. These two control the idle. I believe your problem is the IAC has sludge on its piston, preventing it from sliding back and forth and opening up the idle chamber. You can remove the IAC and clean it with carbuerator cleaner, and also clean the cylinder it slides into with a small brush. You can also buy a replacement fairly cheap at auto parts stores, replace it and clean the cylinder it slides into.

I replaced head gaskets on 2004 dodge dakota. when started it ran rough and lacked acceleration. Code P0300 and o2 sensors showed. replaced all 4 O2 sensors, but still rough idle and code P0300


That's Random or multiple missfire code. Have you checked for proper fuel pressure? Improper fuel pressure will trigger this code if it's too low, thus causing a lean mixture in multiple cylinders.

Hi, my1997 dakota with a 3.9 engine has a rough idle, has plenty of power i replaced plugs, wires, cap,pcv, rotor and added fuel cleaner. its a little better but still has a rough idle


My uncle worked at a dodge dealership as a head mechanic for over 30 years and he also found all of the 3.9 liter engines to have the rough idle. The rough idle cannot be explained but it can be made worse by buildup on the engine. I have a 2001 Dakota sport with the 3.9 and mine does it too and one of the first times i drove it it stalled and its not a Manuel transmission. But onc I changed the oil and put Lucas oil additive as well as regular additives to my gas every month or so it has reduced greatly and not stalled since. Hopefully you find this helpful.
