when i let off the gas and coast for a while, the "service engine soon" light comes on. I recently had it serviced, but they didn't replace the O2 sensor, just plugs, wires, fuel filter, and PCV valve. I was wondering, if I get an O2 sensor, should i pick up the Bosch one? does anyone have anything good/bad to say about it?

Not sure if the O2 sensor would cause that, but do NOT get a Bosch O2 sensor. Go ACDelco if anything.

I'm sure willwren will step in to shed some light on the issue itself though.

Well, my car probably needs one anyway, so at least now i know which one NOT to get and which one TO get.i can always put it in for process of elimination. you guys are alot of help. besides, for the O2 sensor, you just unscrew the sensor from the header, put the new one in with hi-temp sealant, and plug it in, right? I didn't think that an O2 swap was extremely complicated (just as hard as a spark plug swap) correct me if i am wrong, please. Thanks for the replys too!
BTW, does ProZen MotorSports have a website? I see thats where yoou obtained your intake...

The new one should already have anti seize on it. So just unscrew the old and screw in the new. Pretty complicated
