P0135 engine code...

[Steve2kGT]

I just pulled this code on my cobra. I know it is a bad O2 sensor, and in front, but which side? Passenger or driver's side? It says bank 1, but which is bank 1?

Thanks.

Bank 1 is passenger side..

That's the hard to get to one. In fact, I never could get a wrench around that thing to take it off when I was trying to pull the pipe the first time. Anyone know how to get around that O2 sensor to take it out?

There's a couple of different 02 sensor removal tools. One is an offset short socket w/slot and uses a 3/8" ratchet. The other is a socket that goes right over the sensor. I find the offset one seems to work best. I think I got it at Poop Boys. Actually, unplugging the stupid things seems to be the hard part (unless your sensors are frozen). If you can't loosen then cold, then heat the exhaust pipe up and try it hot - being VERY careful about getting burned.
