My car is throwing a CEL i had it read at auto zone. It was a bank 2 lean code. I have had probs with the CEL as soon as i started with the O/R H pipe. I have MILs, but i may have a bad O2 sensor. Do you think that this code could be comming from the O2s or am i really running lean? When i had my car dynoed a while back it ran super rich like high 10s low 11s in AFR. I was also going to ask what is the easiest way to fing out which O2 is bad or should i just change them all?

When they run the computer they can tell you what side. Alot of people believe it or not do not know how to properly use those things. Where I live the people at auto zone know nothing. Find someone who knows how to use the scanner and then call Ford with the specs. I think mine was running rich when I put my H-pipe on with a bad O2.

Yea man you are prob right, because i had my car on the dyno last year and was running rich as hell, but because i just installed my NX kit i want to make sure that it is running perfect.

Both my rear O2's went after the H-pipe install. It took about a month for both to go. But I think they were the originals

On a N/A car? Yuck! You need a tune, problem will most likely go away after that.

i know i need a tune i hope to get an SCT soon, but i just dropped a ton of cash on the NX kit.

i would get a tuner rather than 4 new oxygen sensors, 4 new would be like over 200 bucks....tune you could shut off the rear 02's then sell your mils!
