2001 VW Golf, 2L, 8v, gas with manual transmission. Car misfires and shakes very bad first time in the morning right after rainy night or simply very humid weather, but after it fully warmes up it drives like a champ. On dryed times it starts and runs showing no problem at all. Any one any idea?
You aren't the only one: I just got a 02 Jetta GLS, 2.0L, manual, off a used car dealer's lot, the employees washed the car, stuttered and stumbled for the first 10-15 minutes, once it warmed up, it's all good. My 98 Jetta GLS was just as bad, until I packed all the HV wires with dielectric silicone grease, drove out all the water, and that was that.
