I can't find anyone who can find out what will fix this problem. When I turn on my lights I loose compression and then my rpm will jump to 4-5 and then speed will jump to 65. I am worried that I will loose compression and be stuck in the middle of the road or when speed jumps to 65 I will have a wreck
