EDIT: Thanks for all your help, I suspect the check valve is bad or leaking because I have horrible gas mileage. Both the o2 sensors are fairly new and are both working properly. I'll see how it goes but thanks everyone.
I have a 1994 Pontiac Firebird Formula 5.7L 6-speed manual trans
My ses light is on, I got code 29 from it which has to do with the air pump.
Does anybody know which pins on the harness to check for voltage? The air pump is kinda expensive so I'd like to make sure that's what it is before I replace it.
