    i bought the car with new fuel pump, plugs, plug wires, fuel regulator, timing belt and cam gears. nothing has changed from yesterday till today. the check engine did come on today but went off when i shut the car off and started it back up. i check the tps because i noticed it had been tampered with. i got 4.5v to the yellow wire and .3 at closed and 4.3 at open on the red/blue wire. i tried playing with the timing and when i advanced it 5 degrees it got a lil better response but still bogging and sputtering till 4000. it almost smells like its running really rich?

    try pulling the code anyway, it might still be in there.

    i didnt get gas last night and i jus tried pulling the code and nothing happened. its running obd0 so when i go to work tomorrow i can look down at the ecu when the light comes on and count the blinks. its almost like the car is running in limp home mode until 4000 rpm

    i had a similar problem with my car but was not quite that bad. but my problem was the coil in the distributor. when i took off it sputters quite a bit. i changed it and it all wend away.

    Sounds like your ignition timing is out. If you have acess to a timing light use that to set the mark on the crank pulley to the mark (i believe the 10 mark) on the timing cover with the engine running by turning the distributor
