Sounds like your mechanical timing could be off. Verify that with the engine at TDC, both of your cam gear timing marks lign up with the mark on the back of the timing cover (little raised mark that points straight up right behind the cam gears). If you have to reset the cam at all, make sure you recheck your ignition timing, just as you did. Also, while timing, pull your jumper wire from the diagnostic port and verify that the timing advances to at least 12 degrees btdc
