ok, so i figured out what was wrong. I have a MSD boost controller hooked up to my car and one of the capacitors fried in the circuit board. Upon closer inspection the vacume line that is supposed to hook up to the controller was capped and not plugged in. The car ran fine like that, im guessing because i have mega squirt pnp. so my question now is dose megasquirt retard the timing for the boost? or is the msd controller supposed to do that and if so how if it ran fine without it plugged into the vacuum? Isn't the vacuum line supposed to tell the controller when to retard the timing. anyway car starts and runs but the timing is messed up because i pulled the cas and put a different one in it. but as far as this post is looking dose not look like anyone is going to help because of their egos are to big for this post. so im wasting my time i guess but thats how these forums work hey. People are all I no more than you do nana nana boo boo
