my 89 camaro 2.8l just started some crazy stuff. If I turn on wipers she skips and bucks and dies.Same thing with a/c or blower motor. It does good unless I turn these items on. The only thing I havent done is pickup coil,MAF,or oil pres switch. I checked grounds and took alt. out of the loop,no change. Someone said pickup coil but my exp. is they are bad or good. Any help would be appreciated.

Well I put Anew pickup coil in and no change. Problem is intermit I unplugged est spout problem goes away. Anyone have any ideas??????????
