Replacing front O2 censors
 

The reason I ask is because I got 4 codes, and two were P0135 and P0155....these O2 censor codes are really pissing me off, so if I need to replace them, do you guys know of any places that sell them? And are they difficult to get access to? I know the rear censors are easy to get to, but I don't know where the front's are.

BTW the other codes were P0443 and P1451 (if you know anything about those, please post a reply. I'd appreciate it).

I think you could just torch them a lil bit and they should be fine, but if you want new ones for cheap ebay sometimes has them for like 30 bucks

I also have a cat-less mid pipe (if that helps)

nope. What I notice is that after I let off of the gas, it tends to hang for a second after the car warms up. Could that be beacause of the cold? I live in Michigan.

The front 02s are toward the front of your midpipe. If you get under the car (with it on jackstands) you will easily be able to see them. The PITA is getting them disconnected. Its hard to get your hand up around the transmission to disconnect them.

Once they're disconnected just get a wrench and unscrew them from the midpipe. You could unscrew them first (it would just twist the wires a bit) and then unplug them if its easier.
