I need help!!! My 1996 lt1 is missing and popping under load and hesitates real bad. I have tried different sized injectors. this motor has just been rebuilt. i was thinking that maybe it is something to do with timing. If it is how would I adjust the timing?
Here is a mod list: CC306 cam, 30# injectors, long tube headers, Manual steering, ac delete, smog delete, the exhaust is open at the moment but the O2s are in, mail order tune, underdrive pullies.

Could be the opti - did you put a new one in when you did the cam?
I don't know much but I'm going with opti as the culprit.

I would recheck all your plugs and wires first. Then check the opti. I know it's obvious, but you did mark the rotor before you took it off so that it wasn't installed 180* backwards correct? Timing chain could also be off. My guess is crossed plug wires, though, as that's what happened to me.

Verdad Gallardo To check the computer timing, yes, but that only tells you what the pcm's ignition timing is. It doesn't tell you what timing the engine is actually seeing, for instance, if two plug wires are crossed or timing chain is off.
