Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** for the question. Did your mechanic happen to give you the codes from the computer?
Thank you. Even though it was not throwing a misfire code can you tell me when this misfire was occurring? At all speeds?
Thank you. I have one last question. Does it do this every time you drive it or does it drive fine some of the time?
Thank you. I am really curious to know what the codes are if you can possibly get those. As for the issue, it really sounds like it may have low fuel pressure or that the air flow meter may be failing. I typically recommend cleaning the air flow meter first to see if it changes.
Thank you. I will look for your response later.
Thank you for getting that information. More than likely this is either due to low fuel pressure or a failing air flow sensor. I would clean the air flow sensor first to see if it helps. The fuel pressure must be above 55 psi. If it is not then the fuel pump needs to be replaced.
