Pulled the codes on my flashing CEL yesterday and it also said "bank 2 lean". I'm gonna change the plugs and see if that fixes the misfire. I'm thinking I've got a bad O2 sensor and that's what's causing the car to run lean... Could that be the problem or am I looking at something else??? Any suggestions for stock replacement plugs?

Thanks in advance guys!

its an o2 sensor more than likely or it could be a vaccuum leak either one had the same problem and was the 02 it will even idle ruff sometimes

funny you say vaccum leak. I had a vacuum leak on the rear of the plenum a few weeks back. A vaccum hose had worked itself off and it was idling kinda weird... I fixed that. The car has a constant healthy idle but it seems to shake a little bit. I dunno, maybe it's nto shaking and I'm paranoid.

Sounds like the O2 sensor.

yea maybe the code is still from the vaccuum leak i dunno you cant go wrong changing that 02 sensor whats it cost like 80 bucks i forget

well which side is bank 2? and how hard/easy is it to change on O2 sensor? What tools do I need?

thats funny, bank two is the driver side but cyl. 3 is on the pas. side. maybe you should reset the pcm then check the codes when the light comes back on and see if you still have the lean code

I was just thinking that. Looked at cyl 3 and realized the TB and plenum are gonna have to come off to change the plug. Bank 2 is prolly just cause of the O2 sensor (I hope). I didn't figure the problems were related in any way. I reset the computer and the CEL came back on on the 3rd start. It's no longer flashing (I hear flashing indicates a msifire). I'll swap the plugs and get new wires and then have the codes pulled again. I hate this. I don't have time for this ****.

anybody have any experience changing O2 sensors?

Brute03

no, you don't have to take it off. just diconnect the tube from the t/b and push it up out of the way. for the o2 sensors, disconnect the harness and try to get a wrench on it, it's a tight fit and be careful not to bang it up too much, there're fragile
