LT Headers -> Check Engine Light -> No Codes
I just finished installing my Dynatech long tube headers and when taking the Z06 out for a test drive I get a check engine light flashing. It only happens in 3rd hear under load at high RPM, > 5,000 (didn't have enough room to try any higher gears). The car starts missing and backfiring. It doesn't happen in 1st or 2nd gear and once I back off of the high RPM the flashing light goes away and the car runs normal under light load.
I checked the codes and I have nothing wrong.
I am at a loss for what to look for next. Any ideas?

You are correct sir! Found one loose coil pack connector. I fixed that took it for a drive and it threw a PO300 code. Checked one more time and found a lose plug wire.
It runs like a champ now!
Gotta love this forum.
