it might seem dumb , but i can t figure out how to get the old one out. i cant use a socket or wrench, its too close to the header and theres not enough room for either tool to fit.

Have you tried a crowfoot? If it's too close for one you might have to loosen the header and pull it away from the head a little ways.

a 19mm wrench or 3/4 wrench will work, i have done it many times, make sure you have a bucket you will lose coolant

i finally got it out...it seems like the old sensor had thread lock...do i need to put some on the new one?? the damn instructions say not to use any grease but nothing about thread lock??

and would i need to reset my car after replacing the sensor? or will a code just go away on tis own...it was throwing a P0118 code

I know when I replaced mine (broke it during the header install) I just unplugged the battery and it was fine.
But, I tried 2 off brands (from napa & autozone) and they did not work for some reason. So, I went to GM (I think it was a AC delco brand) and put it in and it worked fine.

Go post your code in the diagnositc section, im sure you will get it in there fairly quick.

Oh, and yea, the autozone one didnt work..

How many times have you started the car since you replaced the sensor? I ask this because the control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.

a few times..dont really know for sure. but i will be reseting the pcm again and hopefully that will do it.

If you stop by autozone tell them you bought the sensor and still have a check engine light. Have them pull the codes and delete it, if it comes back then you have a problem with the new sensor or mabey the wiring.

see thats the thing, the SES light only came on the frist couple of times i started the car after header install. but i had forgotten to plug back in the wiring to the sensor. this was last thursday, ofcourse i plugged it back, but since friday i have not had the SES light on. But i still went in that same day to get it scanned to see why it came on to begin with.
