Ok im not ssure if this is the area to post this if not im sorry and could you please move it. My mother has a 97 grand am and the thing is studdering horribly when accelrating. Once it gets to 30-40 its gone. It only does it when its hot. When its its cold it runs fine. I was thinking maby the mass air.

 

cheack/clean MAF sensor, run some FI cleaner through it, and check for coolant coming out from around the lower intake manifold....replace the spark plugs and wires too....

 

ive done all excepts the MAF.
