So I tried to get an inspection sticker today and was rejected because I didn’t pass emissions, I failed the NiO2 testing… has anyone experienced this or know of away to correct it? Any insight would be greatly appreciated as usual.

Amanda....This is just an educated guess, but if the nitrogen oxide figure is too high, I would suspect that the exhaust gas recirculation is not working. If that's not the problem, then the dealer is going to have to take care of this trouble. ________________ GM!!! BRING BACK OLDS!!!  |

I think the first thing I'll check is the EGR valve because that was also a suspected cause for my idle problem - I'd love to kill 2 birds with one stone

By the way, the EGR can be removed easily. It is a small black can sitting on the drivers side of the engine closer toward the firewall with an electrical connection on the top. You have to scrape off the old silver gasket and put a new gasket on when re-installing but, if you want to unbolt it, you can clean it with carb cleaner and brush out the passages and the shaft inside the passages. This is because carbon builds up on the shaft of the valve plunger. The plunger should move freely with only the resistance of the spring giving force against moving it with no force. The only caution is don't soak the can above as the cleaner could damage the motor windings. If the valve is crudded up and causing the problem, the cleaning almost always solves the problem. Of course the dealer won't take the time to clean these valves since thay can sell you a brand new one!

go to caddyinfo.netgoing.com/howto/egrvalvecleaning.htm this will give you a pick and more details on cleaning the egr valve. Mike did a good job explaining, just thought this link would show everyone a nice pic. And Amanda, a solution to your problem. Set up secondary residence at my house. Re-title it in indiana where they don't do emission checks!  |

LoL I'd love to Ted silly emissions... The best would be bringing our 78 Eldorado (aka Big Red) to get an inspection... they don't even joke about checking the emissions... We're a enviromentalists worst nightmare... getting a solid 14 miles to the gallon highway or city LoL... good times... |

yeah....good times.....i miss it. Driving the Aurora PARTIALLY brings me back to the high school days with my first mustang, but its so different now that life has changed. I bought a mustang almost two years ago after a break with them, but it still just wasnt like the good ole days. Im sounding like im old, but im not. I remember my last mustang, climbing around the backseat at the hardware store to find my screwdriver and finding a GUN underneath my NITROUS tank which always laid on the backseat. I didn't touch it, called the cops, they came and lifted the bottle, took the gun, and didn't say a WORD about my nitrous tank! Good times..

If the EGR were to be bad, should it not show up as an SES light being that it's tied in with the ECM. The O2 sensor is also a ECM controlled device. If your SES light isn't on, then I suggest it to be the Catalytic converter seeing as it isn't an ECM connrcted device.
