I have a 1989 Cavalier 2.0L 4 CYL. Automatic, fuel injected w/ throttle body and when I crank it up it runs fine, but when I shift to another gear, it sputters and dies. I have replaced the fuel filter, spark plugs and also have tried disconnecting the mass air sensor and adding fuel injection cleaner to my gas, but nothing seems to help. I have bought a new fuel filter but I don't think thats it because the one that is on the car seems to be in good condition. I have even taken the fuel injector on the car out and looked at it. When I drive it, It stars out fine but then starts sputtering again and then clears out if I let up off the gas pedal. Can someone please tell me whats wrong with this thing as I am in desperate need to get this car running again. Please respond ASAP and if need be, send me an email to
[email protected] and label the message 1989 Cavalier or something like that so I know what it is.
