Re: Cant figure this out, ignition coil? plug wires?
I had a similar problem but no diagnostic codes. At higher rpm my PT would stutter. And the check engine light came on with no codes. I found the problem and she is screamin again. Three of the plug wires had corrosion inside the plug wires at the coil, bad. Also, the terminal ends on the ignition coil were rusted. This solved my problem. I have never seen rust inside a terminal boot, unless its been underwater. Im pretty sure that my PT has never been submerged (although it does resemble a bathtub)
