Anyone have suggestions on how to look for bad grounds? I think I have a grounding issue in the engine bay. Everything in the car works fine but the there are things under the hood that make me think this. Also, I know of three grounding points for the factory wiring harness. The engine, the left strut tower, and the left fender beside the coils. Are there any others I have not mentioned? Thanks.

 

I don't know about the first generation, but the series four and five FSM's have a wiring section that shows every ground point on those cars. If I were you I'd look in a first gen FSM.
