Hey guys I am new to this forum but already have become addicted and it seems like everyone is very helpful! I love my '05 dakota but I am having a problem with the engine light continuing to come on, the problem I am having is a rough idle and the code is showing a problem in cylinder 3. I have replaced the coil pack and the fuel injector and tried switching it with other cylinders and the code still shows cylinder 3! My only guess is that the valves may be sticky or the injector went again. If anyone has ANY advice it would be greatly appreciated. Thanks alot guys!

 

what code number is it?

 

Sparkplugs?

 

Sparkplug X2.

Lots of 4.7s idle rough... Lots don't.

Bad rings. Does it burn any oil?

Does it make any strange noises? Rattleing or clattering? If so, it may be a lash adjuster has completely collapsed causing the rocker to unseat and interfer with valve operation.

May be time for a trip to a trusted dealership.

 

I had a problem in cylinder 1 and it went away in like a day lol...did yours say it was misfiring? It might be a spark plug like the above said

 

the light has gone on and off several times and for more information it is a 3.7L and I replaced the coil pack and injector. Thanks for the replies guys!

 

spark plug or head gasket

 

thanks guys I ended up taking it to the dealership and they said everything was fine but the last guy that worked on it forget to reset the computer so they did.
