Author Topic: flat-spot when accelerating?? SydeWayzSix ¯ Member # 2222 posted                              My car has been experienceing this problem on and off. Basically, when I am in 1st or 2nd gear and I floor the gas pedal, it sometimes feels like its falls on its face...but then begins to pull hard right after. It only occurs when the RPM's are below 3K. If I am above 3K RPM and then floor the pedal, it seems fine and pulls hard. Someone told me that it could be due to a faulty MAF sensor, but I'm not sure. Any ideas?? -------------------- 1989 Notchback "SF Giants" edition...

I would clean the MAF sensor also. -------------------- 89 LX Notchback ex 4cyl, 14psi 02 Harley F150, 15psi Posts: 8521 | From: Fairfield | Registered: Jul 2003  |  : SydeWayzSix ¯ Member # 2222 posted                              I'll try that. Also, how do I clean the MAF? Do i clean the wires/connector, or the inside of the MAF?? -------------------- 1989 Notchback "SF Giants" edition...
