I have a 93' Toyota Tercel that stutters and losses power during lower RPMs in 2nd and 3rd gear. It only occasionally does this and seems to do it more frequently and sever in 2nd gear.

When it does do it, it does it for a few seconds and then it starts reeving up and accelerating normally.

Any idea what the issue might be?

Lack of acceleration,chugging,hesitating********,bogging,misfiring etc. could be caused by one of the following below


Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.


Note:If it doesn't apply disregard it and keep testing.
