i have a stock 93 sc (recently rebuilt) that for some reason will run perfect until (no known cause)the check engin light will come on and rpm drops to about 1000, the car then feels like it's running on four cylinders, and if you try to acclerate you can't go over 0 psi of boost or it will try to die. this happens intermittently when ever the car wants to. i've changed fuel filter, air filter, checked all plug wires (plugs are still pretty new, 10k ) and ran the codes (only code was 33) after a while of this the engine light will go out and the car runs perfect again???
can anybody help?
thanx
