Pontiac Problems? Ask a Mechanic for Answers ASAP
Hello, my name is***** the check engine light start flashing? Is check engine light usually on? Thanks.
This most likely means ignition coil or ignition module has failed. I'd recommend replacing both with a used assembly from salvage yard. Otherwise to figure out what one has failed during problem you will need to test spark on all 4 coil leads. If it is missing spark or weak spark on only one cylinder replace coil. If it is 2 cylinders replace ignition module. Let me know if you have more questions, thanks.
Sounds good, let me know how it goes. Thanks.
