mass air flow sensor

Asked by bamcken Jul 24, 2008 at 04:07 PM about the 1999 Pontiac Grand Prix

Question type: Maintenance & Repair

I have a 1999 grand prix gt.  My service engine light came on and i went to auto store and used the computer.  It indicates the mass air flow sensor is problem.   So I tried some cleaner and reset the light. all was well but then the engine started a little rough one morning and it came back on. the engine runs great after that initial start, idles fine etc...  I would like to just replace the mass air flow sensor but want to make sure its not something else.    The car has about 110k miles.   On a 150 mile trip the light actually went off but when i restarted car after a bathroom stop, it came back on.    What do you think.   I have taken readings at the auto store several times.  always   mass airflow sensor.
