i just installed a 224/228 114+4 lsa and stock ls6 heads on a t/a. the car was tuned but i keep getting a p0300 multiple missfire code. i hooked the tech 2 up to and i get a few missfires from each cylinder at idle but none when hitting the gas. even when i ease on the gas pedal, not a single missfire. i'm sure this is common after a cam swap but i don't know if the code needs burned out through hp tuners or if this means there is an engine problom. the car runs freakin awsome. so should i just elminate the code or.....????

 

Yup very common, just delete the code.

 

thats normal

 

yup normal, had that here too...my tuner just turned the misfire on a low setting...no probs since.

 

ok thats what i thought, i tried a search but i couldn't really find anything. thanks for the help

 

Yep, I keep popping that code too until I can get it completely turned off. I also get a improper O2 heating code now that I never got before the cam swap. Both are normal & won't hurt anything.
