Hey, I installed grounding wires on my car a while back, and ever since, my car idles usually at 3-400 compared to i believe 800? well i read something about grounding wires making your car's idle a bit lower, but i was wondering if this was actually so. If this is not, is there some way i can reset something to make my idle normal. please help. thanks

 

There is no way your car idles at 300-400. That would be below the starting mark. Take another look..it's probably sitting around 600-700. That is what mine idles at w/ my grounding kit.
