1998 Grand Prix GT Stalling with P0336 and P0302 Codes - How to Fix?
I own a 1998 Grand Prix GT with a 3.8L engine. The vehicle frequently stalls while driving—sometimes it dies completely, other times it just hesitates. When it does die, the engine cranks right back up without any issues. Today I scanned the system and found trouble codes P0302 (cylinder 2 misfire) and P0336 (crankshaft position sensor circuit fault). I'm looking for insight into how to diagnose and fix this issue. Any advice on whether these codes are related or if one is causing the other would be greatly appreciated.
P0336 indicates a fault with the crankshaft position sensor or its circuit, which could be directly contributing to the misfire detected by P0302. On the 1998 Grand Prix GT engine, this is a common issue—fixing the crankshaft sensor circuit should resolve both problems. There are several potential causes for misfires on this model, so addressing the P0336 code first is recommended. Good luck, and please update if you find a solution.
