One more question, When I unplugged my OVP on my 87 and started the car, the car ran like s*#t. so I reinstalled it and then it ran fine again. Does this mean , my Tach, A/C, and ABS issues are some other problem?
What else to look for? Haven't been able to find out yet weather or not I have a CPS and What symptoms it causes when one goes faulty.

Thanks again for all the thoughts and advise so far.
Anyone's additional thoughts will still be greatly appreciated.
