Unfortunately i walked away defeated tonight,had my vehicle on jack stands so i was too scared to hammer it.Tomorrow i will try a heat gun and a WD 40 and if that doesn't work,i'm bringing the vehicle to a mechanic. Thanks for this video.
Changed one on 94 Cheyenne yesterday soaked wth kroil 2 weeks in advance finally got time to work on it tried vise grips no luck. Got out propane torch but decided against using it I worked on boilers for 40 years got out my pipe wrench and old Betsy my ball peen hammer after 3 blows it broke loose then used the vise grips to remove it. My boy took me advance auto pick up a Bosch for 37.00 plus tax wires were not as long as original but got it together boy my truck sure runs better. I'm 71 still at it.
I still can't get mine off. It wants to slip on my 2005 Mercury Grand Marquis. I used PB Blaster penetrating oil and finally after fighting for hours I finally gave up.
@@bolognablake thanks. Do you by chance know what appears to be a sensor just by the fuel pressure regulator? Not the air intake temperature sensor. Between that sensor and the fuel regulator. It is less than a 1 inch from the fuel pressure regulator.
Besides the wiring issue, was there anything else going that led to believe it was a bad o2 sensor? Dealing with a hard start/throttle response issue with my 88' 4.9l
Heat the pipe more than the other so it will expand from the o2

One other trick I saw was to put a hose clamp on the O2 sensor socket - keep it from spreading .
You Don't heat up sensor you heat up the NUT that it screws in to... HEAT EXPANDS,, therefor you want the NUT to expand and LET GO of the sensor,,,,
Have you any clue where to ides

I forgot to add, this was on the upstream O2 sensor. The down stream O2 sensor was a piece of cake but the upstream is a nightmare.
Thanks for posting this. Were you keeping most of the heat on the bung or just heating everything?
Mine come out easy with a 7/8 open end wrench after spraying it with stuff to loosen bolts.
Is there only one O2 sensor? I have the same year and 4.9
Correct, there is only one.
