o2 sensor is bad, but is it alright to drive with for a while, and by a while i mean like 2 days haha i figured it wouldnt cause to much problems

 

Which one?

Front bank will kill your MPGs and probably make you run pretty rich.

 

im not sure exactly which one, but the mpgs dont matter to me for the few days i just wanted to make sure it wasnt going to do any real bad damage to the engine

 

It will run ****ty most likely (if it's the one on the rear exhaust manifold)

The one by the cat shouldn't make a BIG difference, but you'll still see a decrease in performance/MPG

 

sweeet, thank you. yea its only two days and im not going on any big trips just around town and what not just cant get to it until tuesdayish soooo im not too worried

 

If you don't have any get a can of PB Blaster and spray around the base of the O2 sensor about 2 hours, then again about an hour before you want to remove it. Otherwise it will be a royal pain in the back side to break it loose. Once it's out it's a good idea to run a M18 X 1.5 thread chaser through the bung before installing the new sensor. If the sensor doesn't have anti-seize on the threads (most do) be sure to put some on it. Use either an AC Delco or Delphi sensor for best results.

 

sweet! thanks for the tips man!

 

No problem. You're also going to want an O2 sensor socket (has an opening up the side for the wire) and an 18" (or longer) breaker bar or a piece of pipe you can slide over the handle of your rachet for leverage. With all the heating/cooling cycles those things go through they can really be stubborn coming out.

 

honestly i've never had a problem getting out the ones i've pulled... but i am a 260lb former college football player , been breaking my snap-on ratchets and bending my snap-on wrenches fairly regularly since i started automotive school... glad they have a lifetime warranty sucks for them they don't make them as good as they used to. I've never had a problem with the antiquated snap-on tools my classmate has.

 

If you haven't come up against an O2 sensor yet that refuses to budge then you have been graced with a stroke of good luck. When you get out of school into the real world and turn wrenches on a daily basis I'm sure you'll encounter a few. I've never broke a snap on wrench and only stripped the gearing on one of their rachets. That was many years ago when I accidently grabbed my fine tooth rachet instead of my coarse tooth rachet and the torque was too much for it. At least snap on replaced the racheting mechanism for free...even though it was my fault it broke.
