Last month I fixed the skip and the rear end. Now I can't tell if I have the skip back or the trans about to let loose. It just chugs shakes shimmies anything but get up and go. Would an engine light turn on for a bad trans? I don't think it's a skip because no engine light. Guess bulb could be blown

 

Bad COP

 

COP’s and Plugs... mis-fire’s do not always set a DTC

 

If one of the cops were bad would it smell like an electrical fire when it burns out?

 

Problem fixed! Thanks guys... The damn spring inside the cop boot was broke. Really appreciate the input. Thank you

 

Well that was an easy fix. Good news.

 

Your welcome.
