Run the codes. Flashing SES means danger to manifold, but typically, you can just tell it to shut up and continue with your 5th stage of NAWS. j/k.

It's misfiring for sure then. If you changed the plugs and wires, it's probably a fueling issue. Crappy fuel filter or fuel pressure regulator could cause that. When you pulled the first plugs, what did they look like?

How about some different punctuation than just "..." next time??

did you check to see if you had oil on the MAF??? - it will mess with the readings and cause all kinds of trouble.

Ls1 fuel pressure typically is around 58. When it blew it was probably enough to supply the motor with enough fuel to run but not enough pressure to run correctly.

your car would not run at all if it was not getting any fuel at all, I am confused.
