Help: o2 Sensor will NOT come out

if all else fails to remove the stubborn O2 sensor here is how we do it up here in the salt belt,,, knock off the the upper shrouded sensor guts then heat just the base of the sensor with acetylene torch (mapp gas may do it) then chill with water, when you heat just the sensor it tries to expand but has nowhere to go so it displaces itself then when you cool it it shrinks ,,, if ya dont have gas a CAREFULLY placed weld on the base will also work,,,, This is the trick i learned many yrs ago at a good ford dealer Mark in upstate NY

How can i get this thing out...everytime i put my full strength into truning the socket wrench, the O2 puller slips on the O2, and i dont want to round it off....?????

like sai above, heat exhaust up first.. i ran mine for about 10-15 mins. then took off intercooler used o2 socket from autozone and it came right off....

1988 t/c for $500 fully stock for now over 250000 miles....but still runs ....auto tranny.. and finally street legal....yay

we pulled codes, and it stated the HEGO was not switching, and was reading either rich or lean, i cant remember which

so we tried disconnecting the O2, and it helped a decent bit

got it off....used a 7/8" combo wrench and let the car warm up for 15mins....one good pull and one cut arm later, the o2 broke loose

Well, if i beat you when i was stock, what would happen now?

Isn't it amazing how many parts are positioned in such a way that they require at least one cut (requiring a bandage) to remove ?

yea, this one looks like it could like it could leave a mark...so i have been thinking about getting a thunderbird symbol tatto to even it out...lol...talk about being crazy over a car...i passes up a 99 VR6 Jetta 5spd for $3k because i didint want to take maoney away from fixing/modding the bird....so its only right i get the tatto

down here in fl, we call burning yourself on the turbo a "turbo tatto" and a scrape with blood or worse,"battle scars"

now these are required to remove, replace or repair, anything on a t/c. if you walk up to the car and cut your self, then grab the hot turbo with both hands, then everything from there on in will be smooth sailing, you just have to get the cursing out of the way first.

90% of the time, an O2 not switching code is NOT due to the O2 sensor being bad!! A 41/42 is MUCH more likely to be caused by fuel pressure problems, VAF / TPS problems, FPR problems, vac leaks, etc. Exactly what code or codes did you get? What part of the test? KOER? CM?

i dont remember off the top of my head to be honest

it was engine off

at the same time, we changed out the plugs for some motorcraft, gapped em, determined that it needed a TPS (tested the voltage, no matter what youd do to it, it would read .02), and got a code 14
