02 Dodge intermitant Misfire Driving Me Crazy

[plymouthsrock]

If the miss is consistent enough, a power balance test may point you in the right direction. This involves disabling one cylinder at a time, and seeing which one causes the LEAST rpm drop. Disabling can be done by either disconnecting spark plug wire or injector, whichever is easier. If not I would suspect EGR trouble (valve not seating), which the engine at cruise can handle, but not at idle.

Daniel and everyone that helped me with this.THANK YOU... I sold it! Had it listed on Craigs list for $4000. The new owner is a mechanic. He was aware of the problem and said his other van, (one like mine) had the same problem and it was a wiring harness issue for the injectors. Didn't seem to be to concerned....anyway thanks again!

Was this a intermittent misfire on the same cylinder?

I once found an extra fuel injector seal in the fuel rail causing the same type of symptom.

Congratulations,
Divorce is one way of resolving three of your problems!
(1 van + 2 mechanics) = 3 strikes

** Copper wire breaks, just like old school copper spark plug wires.
Constant bending, movement (rpms), heat, and time = broken copper wire
