well i got my opti plugs and wires replaced. The check engine light came on and the shop said my right bank o2 sensor is dead. It seems to run ok in open loop, but when it warms up it runs like crap and the exhaust wreaks of fuel. Ocassionally some smoke along with that. Would a dead o2 sensor cause the car to run too rich?? too rich to bog during acceleration??? Is it difficult replacing a right bank o2 sensor on an lt1???

To answer your first 2 questions, yes a bad O2 can do all that. The last question, I don't know, someone else will have to fill that in.

sounds like O2's to me... they should be fairly easy to replace.

Spark plugs on the other hand...

oh, and i would recommend www.sparkplugs.com (for your O2...) try that first

well i changed my o2 sensor and the car runs a hell of alot better. No more bogging during acceleration and no more rough idle. it was a real pain getting up to the right sensor but with time it finally came out. im gonna replace the other two o2 sensors also just so this wont happen again. thanks everybody
