you probably should have thought about that before you gutted it. do you have a 3800 in your impala?

> here’s the trick. if your car is 2000 or older, you can have up to 2 items not completed on the readiness check. if 2001 and newer you can have only 1. usually EVAP and catalyst are the last 2 to complete. if you’re 2000 and older, drive the car 5-10 miles and give it a try.

that isn’t really a trick. the evap monitor typically doesn’t run when it’s cold out so people who have emissions testing in the winter months won’t have evap complete if they’ve recently cleared codes.

neonracer i’m not sure who watches these boards but they are public. i would never mention anything like that
