the good news is im sure bill boost will be back tomorrow, he's got all the answers lately, link it to test bill boost maybe.
Changed the valve springs and retainers to the G8 ones. I have a VS cam in it.

I think your off a tooth with the back fire, meaning your intake valve(s) are probably open when they should be closed.

But before you go tearing back into it, make sure the cam and crank sensor are hooked in. I would seriously fix the cam sensor connector. I would go to a junk yard, and cut one off the engine loom, and cut and splice it in, solder it, and seal it with heat shrink, and then recover it in the loom for protection. You NEED those clips on there to keep the connection.

Wont cylinder 1 be at TDC, when the timing dot is at the top? I was told to just line up the timing dots, and then the camshaft and crankshaft will be timed properly. I wonder if it misaligned by a tooth or something, once I got it installed. Is one tooth off enough to cause this serious of a problem?
