Dear all Ls1 tech Members...
I really need ur help in my problem.
I have a camaro ss 2000 model T56 with full bolt-on's but with out any cam..
anyway my car when i give it full throtle in the 3rd gear and great the check engine light start blinking and when i check the code it comes the P0300 code..
i changed a lot of things in my car to fix it like the coils, spark plugs, head gasket, wire plugs, fuel filter ....etc
did anyone faced the same problem.....Need ur advice please

do you have access to a scanner software? If so scan the cylinder misfire count and watch to see if 1 goes really high at the time the P0300 comes up...

If you've already changed all of the coils, plugs, wires... then maybe it's a failing or clogged fuel injector...

If you see 1 cylinder w/significantly higher misfire counts than the others, try to swap the injectors between cylinders and see if the problem follows

also double check that none of your plugs are cracked, and that all the plug wires are "two click" tight.
