GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hi Im David. what was the reason for replacing the fpr in the first place if i may ask?
was it running rough and thats what led you to replace it ?
so its starting ok now? but cutting out at times?
you're going to need to monitor the engine while driving and capture the data with freeze frame when the fault occurs. otherwise we're just guessing.
did you monitor the engine while driving? with a problem like this, its pretty much the only way we are going to be able to see what is happening to everything when it occurs
do you still need assistance?
