Maintenance/Repairs

This was a topic i came across on11/11/2001. There was no cure for the gentleman, and I wondered if he or anyone else has a solution for: Car drives excellent in dry weather, smooth, no hesitation. or misses. While driving in the rain, the car will start running “REAL” ruff and then will stall. I try to start it and the motor just turns over, sounds like no gas or not firing. I will keep trying and after about 6 times it will fire, start and quits, if lucky with a few more tries I can get it started and needs to rev up to 4,000, sometimes it will stay there with a miss or RPM works down and quits. When lucky I can nurse it home and then won’t start for 3 days.I have replaced Crankcase position sensor,(made shield for side at wheel well and shield on bottom), camshaft sensor, spark plugs and wires, had coil packs checked, checked plate that coil packs set on, cleaned battery posts, checked and pulled on wires to coil pack plate, none lose and had continuity, put silicone sealant at end of wires to protect from moisture and hold them in replace.Sprayed top of engine with silicone spray and flex seal. Even had intake manifold gasket replaced in case it was sucking in water. I apologize for long entry, just trying to give you all a complete list. HELP this has been going on for 3 years…PS: replacing crankshaft position sensor did some good, it makes for faster starts.
