2005 dodge dakota slt, 4.7L 5sp auto, replaced engine at 214k with reman engine. immediately got rough idle at start up hot or cold. multiple misfire code/ bank 2 rich condition.


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.

What causes engine miss at idle under load?


I'm not sure what you mean by "under load", maybe with a/c on, etc. Also is it really an engine misfire or a rough idle. If it really is a misfire, a scantool at your local parts store should be able to read a code for that. Sometimes a rough idle could be due to just a cracked or disconnected vacuum hose or dirty throttle body. You didn't say whether it runs ok at highway speeds. Sometimes a rough idle can be cleared up a lot with throttle body service or injector flush. Sorry, this is the best I can do with information provided.

you have a bed coil (s). That's what causes misfire. Your DIC should be specific about which cylinder coil you're having trouble with.

Drive rough with foot on gas


if that is engine related, we dont know here , we cant drive it and feel it.
if that was engine vibration, its most likely MISFIRE.
the #1 cause of MISFIRE, is not doing the 60k mile tune up.

is the CHECK engine lamp off driving? if not scan the ECU/PCM
any scan tool works. (new types) even a $9 tool.
scan it for P03xx codes, misfire.

rough hot or cold engine.
rough only driving and not at idle and not racing RPM parked?
does engine ever stall>?

Engine Code 67 - cylinder 2 misfire


HI, this could be three things here causing this misfire. One, it could be a bad plug that. Two, the wire could not be getting the right current flow from the distributor/coil. Three, you could possibly have a bad valve spring that is not preforming up to specs, causing the cylinder to combust in a unstable state. i woudl check the above areas.


please rate and god bless.

Ford Escape 3L 2002 Rough idle


generally, when the engine is washed, water gets trapped behind the spark unit and stays there, creating a shorting path for spark plug current. best to dis-mount the spark unit (follow plug wires back to source) and dry and clean it thoroughly.
