Sheesh even my local Chevy Dealership only charges $20 to hook up the ODBII code reader and if they think its fuel pump that is another $10 to put the pressure gage on to check it. Man you got ripped. I would file with the better business or some where about that RIP OFF.

Hey, just a quick note: u said it was the o2 sensor, but i once had the check engine light come on just after replacing my gas cap with a lockable one from Farm n' Fleet, but once I removed it and put the original back on, the light went off - it's a "air/gas/emissions" deal that signals the light to come on.
Be careful buying AutoZone stuff, most of it is like getting generic pharmacueticals versus name brand...

Yea things like gas caps I buy DEALER only. Its the only way to ensure a TRUE fit. Seeing as these ECM's are getting supper PICKY more and more every day.
As for O2 sensors I buy Bosh, its what the dealers use and I can get them cheaper threw supplier then from dealership or part stores.

Bosch is NOT what the dealership uses. If your dealer uses them, find another. Any GM dealership should only be installing Genuine AC Delco sensors on GM vehicles.
In my experience, Bosch sensors for GM vehicles are one of the worst you can buy. Genuine AC Delco sensors have much higher activity when you look at the sensor traces through an ocilliscope or compatible scan tool. I have looked at Bosch, Borg Warner, NGK and AC Delco in the same vehicle all brand new. The all out highest activity sensor was the AC Delco with the NGK not too far behind. The Borg Warner and Bosch had less than half the activity of the Delco. The expected life span of an O2 sensor is directly proportional to the activity when new. Higher activity, longer they will last (all other things being equal).

Odd, I have had nothing but good luck with the Bosch stuff with my other GM's. I have had to replace the AC DELCO stuff more offten when it came to O2 sensors. Guess it all falls upon the supplier and the user.
Its not like I buy them from the auto part stores (lower grade quality), I buy direct from Bosch.
