Customer Question

91 Cavalier RS 2.2L, car will crank and start fine but has no power when accelerating. Fuel filter was replaced and pressure checked, around 11 psi. It feels and sounds like the engine is fuel starved but I'm not sure why.

Hi there,

Check for a plugged catalytic converter. If you can, remove the front O2 sensor and then drive the car and see if it has more power. Many times the converter can break up and block off the exhuast, this causes low power and a lean condition. Car will idle without a problem but not have any power when accelerating.
