Mine seems to be advancing when it is hot vs cold.

I always gapped them at 0.035" myself. The Vortec cap and rotor needs all the help it can get. The large cap HEIs are the only ones I trust not to carbon trace and crossfire at 0.045" or more. Once I start building cylinder pressure with even a large cap HEI, I close the gaps to 0.035" on them too.Was your cam installed straight up with new timing set?
Also, where you 110% sure injector wires not mixed up?
Also I remember someone having misfires from injectors not being seated all the way in there hole, something to think about.
If you have a timing light though, I would definitely confirm if it has constant spark on all cylinders and eliminate the ignition system.
Also as has been stated try plug gap at .045.
I would update your first post of the thread. Easy to find, and then everything is in one spot, and it's easy to refer people to it.Maybe i should post a log of what i have done or replaced?
Good. Make sure to validate PIDS after you connect and it should poll the ECU and it'll tell dash command EVERYTHING it is able to allow it to see. Then you'll be set.I set Dash Command to a 2002 chevy Express van. I'll see what it says in the morning.
