Hesitation when accelerating
Asked by Melis1028 Jul 11, 2012 at 12:51 AM about the 2001 Pontiac Grand Prix
Question type: Maintenance & Repair
I have 01 Pontiac Grand Prix, the last couple weeks it's been
hesitating when accelerating. Spark plugs and wires just
replaced, new fuel filter replaced and injectors cleaned too. I
took it in today to and independent repair shop and he said
there were numerous codes for sensors etc. that showed up
so he needs more time/money to figure out exact problem,
but did mention possibly mass air flow sensor. What is the
average price to replace mass air flow sensor? I don't want to
be taken advantage for repairs as I have experienced before.
Any advice is greatly appreciated!

Thank you very much
more information is needed, did garage give you the codes that came up?
No he just rambled off numerous codes, misfire code and about 3 different sensors. He called back and said it's the crankshaft sensor and would be $220
that would cause a misfire, good luck

Try cleaning the throttle body , relearning the idle and putting super unleaded or 100% gas also clean the fuel system lines to the tank. Also check your accelerator pedal and throttle body sink make sure they are close together
