My son got the 2001 GTP hand-me-down. We just finished some maintenance with a new crank sensor, (CKP) harmonic balancer, water pump, supercharger isolator and belts. We did this maintenance because it died and wouldn't immediately restart. When it did restart, it would run smoothly, then the engine speed would occasionally drop and nearly die. Got it towed home and changed parts.
It no longer dies. However, both before and after changing the crank sensor the engine will occasionally cut out under acceleration, for no more than 1/2 second. Other than that it runs fine. The check engine light hasn't come out, I have not yet scanned it for stored error codes though. One thought that occurs to me is the throttle position sensor (TPS) may have a dead spot. I'll check this with an ohmmeter in addition to the code scan this evening.
Anything else I should check for? Do these symptoms describe a well-known common problem for this car?
