We have a 98 durango slt with the 5.9 magnum. It all started one day when the wfe came home from work. It had a miss, I replaced plugs, wires, cap and rotor, still has the miss.
We took it to the garage, mechanic replaced all sensors, distributer, plenum gasket. Since then the idle has gotten worse, will not stay running. I even replaced both timing gears and chain thinking that may help. NOT..... I'm ready to blow the D*# Durango into little peices.
Help Please?????

 

Sounds like a similar issue that another member had... the fix was a new PCM...

Thanks old school, I've tried everything else, I'll try that next.... I'll keep ya posted on the progress.

 

Also I would replace the coil seeing how you've done everything anyway, and re-route the wires to the TSP requirements.

Any codes?
