Question about 2005 Chrysler PT Cruiser
PT Cruiser engine light is on. Codes are saying that engine is misfiring. Mechanics still looking for cause after 3 days.
They are still looking for a cause because it isnt misfiring right now or because they cant find the cause of the stored misfire codes ?
If it is misfiring right now and they cant figure it out then perhaps you should find new mechanics !
I have seen a lot of bad coils on the PT.
Misfire is usually caused by spark plug wires first, spark plugs 2nd, and coil third.
If it isnt misfiring now, spray down the wires with water. If it misfires after that replace the spark plug wires and spark plugs and try again.
If it still misfires then the problem will likely be the coil.

Lots could be the cause plugs, wires,coils,injection system need code to specify
