Engine Performance problem
1996 Chevy Cavalier 4 cyl Front Wheel Drive Automatic 200000 miles
The engine vibrates like it is starving for fuel, at idle and while driving, but the engine code reads a rich mix. The car has no power and will only get up to 30-35 mph if I floor it the car bogs down hard and will only accelerate if I hold the peddle steady.I also get a clunking noise that gets worse the closer it comes to shifting, which seems to be comming from the throttle body.I have checked plugs, wires and packs. Replaced fuel and air filters. Checked compression and replaced the map sensor. Checking the fuel pressure is just bout the only thing I have not checked yet because I have to cut into the fuel line to run a pressure tester. Do you think its the PCM or fuel pump, or another issue alltogether?
have the same problem?
