I am having problems with my car in other ways you may be able to tell me something about. It is very weird but if i have my a/c or heat on my car won't aferfire at all but if i dont have it on everytime I let off the gas aboe 1800 rpm it starts afterfiring like crazy! I dont know whats gonig on, also I have a powerful sounds system and after playing it, the car wont drive/accelerate as well. The guys who put in my engine were looking at it to try and fix it and noticed the voltage was jumping or sometimes reading low when the car was hot. Any suggestions, I am lost with this and I am sick of bringing it back to these people.

make sure they hooked up all of the ground straps. Or just run a new ground from the engine to the body. heat equals resistence, hence lower voltages.
