Let me start by saying I'm new, but often enough read the forums and now I've got a question.
i put a sunpro tach in my 97 cavalier, with out a stock tach. Its been working, but as you probally assume it doesnt read right. so i tryed a jumper wire from each side of the coil to the tach. the car dindt like it, threw the check engine light on and died. so that didnt work. Put it the way it was and it still just doent read right. So my question is can i go to the crank senor, not the crank postion senor right? any ideas other than the tach adapter would be sweet thanks.
