Re: 1990 LT5 emissions fail
Welcome onto the boards there...
Hows the burn temperature? Hotter burn means higher NO's, so you want it to burn a little cooler. This will also boost HC's however; what was the HC count? WAY under limit???
You're only 10% over limit on NO's; if you can bring down the burn temp a little, you should be ok on it...
