I have a problem with my car misfiring at a low RPM. from about 1500 to about 2500 it misses. Once you ecxeed the 2500 it lines out. I have a 302 crate engine bored out to a 306, MSD 6al, 70mm T.B., off road X pipe, pullies, mac equal shorties, cold air intake, and 3.73's. I thought it was the itming, so I took it to a local speed shop and when they adjusted the timging, it did nothing. After I left the shop, it got worse. I replaced the cap and rotor along with the plugs, and now I am back to where I was. Any suggestions would be greatly appreciated.
This started after I installed the MSD, x-pipe, and the throttle body.
