i have a 2001 grand am 2.4l. i have replaced the spark plugs/boots and big white thing that connects the coil packs to the plugs/boots.

this issue has been going on for a while, but the check engine light would come and go. before the tune up. the car had lots of 02 codes, after the tune up P0130 was the only one to come back. i guessing the computer just notices the incorrect fuel mixture after the car messing up and then comes back to life.

the car falls on its face just when acclerating from a stop but not every time. for about 3-5 sec. then come right back to light. if i keep my foot on the gas it slows down more. so i stop giving it gas and off i go.

can anyone help me??
 
change the fuel filter, and air filter if dirty, and do a fuel pressure test. If low the pump maybe going.
 
I dont remember the exact range but if you are around 40, it's good.
