02 Sensor
I have a 1995 Mustang Gt. I have after market exhaust. I was wandering if my 02 sensor could cause bad gas mileage. I heard it could. I was wandering if you could clean them or if you have to replace them?? And where are they located at? Also how hard are they to clean-change?? Let me know thanks.

It sounds like I need to replace the o2 sensor in my car as well because I have the same problem as the person above where my light comes on after the car warms up. I went to 50resto.com and was going to order one for my 1990 5.0 convertable auto and the part # I get depend on an O.E. ID number and there are 4 differnt ones for my year. I am wondering how I can tell which one it is that I need.

I beg to differ on that comment, I just swapped out my old h-pipe and headers and my driver's side 02 sensor was in there GOOD, I ended up buying new ones because it was nearly impossible to remove the old one. But you're car has a few less years on mine so it'll probably be easier (depending if there is a lot of rust on it etc.). It's going to run you about 80 bucks for two new ones though.

A BAD O2 SENSOR WILL NOT CAUSE THE COMPUTER TO STAY IN OPEN LOOP. The only thing that causes a the computer not to go into closed loop is the degree of the coolant temperature. A bad 02 sensor generally gets stuck at lean 0.00-.2V and will cause the car to run rich yes, so if you can't verify or remember when the O2 sensors were replaced last, then I'd try and test them and then replace them if they're lazy or shot.
