1997 Toyota Corolla Repair Question
Asked on February 23, 2011
Distributor
I have a 97 toyota corolla and it occasionally runs rough where it is difficult to accerlate past 30-50 mph and while it does that, as soon as you ease off the gas pedal, the car comes immediately to a stop. Then you cut the car off and 30 mins later, its back to running normal. I have had already had oil change, plugs, wires, distributor cap done. What do you think it is?

Knock sensor
Manifold absolute pressure sensor.
EGR Valve

Foul/defective spark plugs.
Open spark plug wires.
