Codes 135 and 141 came up. Both relate to the o2 sensors. I had both changed with OEM sensors but the codes remain. I now also have a stumble when the car is at a stand still and idling. The stumble comes and goes. Where should i look next? PLEASE HELP!!! 2002 svt focus
Just by chance you dont not have an A/F Gauge hooked up?

No, but is something i can do on my own? Where would i hock it up?
Let's start at the beginning ... your car threw codes 135 and 141 ... you diagnosed the problem as o2 sensors ... replaced them but the codes remain ... you now have a stumble that you didn't have before ... is that it?

What other mods ... what o2 sensors did you have before ... how many km ... what other repairs / replacements ... etc ... a bit more detail might help get to the bottom of this.

Im thinking, he was thinking that could have been the problem...

Are you sure both those codes have to do with 02 sensors?
I found the problem!!!!Fuse # 18 in the engine bay was blow. It controls the o2 sensors heaters. Wow all that trouble for a $2.00 fuse. Thanks for the imput. I hope this helps someone else out in the future.
