@ Docfixit I sent my car to a shop to test the electrical for me and they told me that i needed to reprogram my PCM or something was wrong with my pcm and i needed to take it directly to Chevy for service.
Do you have any friends in California i can take this car to personally? This Vehicle is not a regular Camaro. I got this car from a retired Lt. from the highway patrol in Oregon and this car has many Chevy Add-on's i do not trust with just anybody.
I took the car to Pontiac/Chevy dealer when I threw my timing chain and they told me i threw a piston and i had a hole in my piston. I took the car home and fixed the timing chain myself. Same motor is in it now. You can see why i Try not to take my car to shops because i just get screwed for money i do not have.
She runs so great. I replaced ignition control module, distributor, opti wiring harness, coil, crank sensor, alternator, everything with ignition short of the PCM and the entire motor harness from the PCM.
