Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi there, I am CAm. Sorry for the delay in getting to your question. Those 2 codes, do they ever reset? Also can I get your VIN?
Can You check the code P0186, that does not match in the GM manual.
Is there a possibility its was a P018C? IF not then it may be a false code and is a result of a bad fuel pump module.
