Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I'm an independent contractor here at Just Answer.
Will this occur in neutral or park?
When this occurs are you touching no pedals?
How often does this occur?
Thanks for asking your question and letting me try to help you.
When it has occurred in park were you applying brakes?
Thanks, ***** ***** wanting to rule out a vacuum leak in the brake booster, which we did so.
Spray clean the MAF sensor using brake cleaner, then spray and scrub clean the throttle body and bore using brake cleaner and a tooth brush then retest. If it occurs again then you need to replace the PCM.
If you are unable to rate my response GOOD or EXCELLENT now. Please let me know why ( if I need to help more) and when you will be able to.
Follow up/Reply as many times as needed before or after rating.
PCM is the powertrain control module. It is under the air filter box.
I like to stay in contact with my customers that appear not pleased, still working on the concern, or have not rated yet. I assume you were not pleased with my help. I hate that you have spent money to get an answer but left not happy. Can you tell me why, or can I help more. If its more help you need just reply and we can pick up where we left off.
