[L98] How Hard Is It To Replace The O2 Sensor?
 

Folks,

How hard is it to replace the O2 sensor on an L98? Do I really need to "elevate" like the service manual says?

Getting in deeper and deeper...

I can reach mine from the top or the bottom. You may have to go underneath to disconnect the pigtail from it's connector. After that, put a 7/8ths" box or open ended wrench on it and turn counterclockwise. To reinstall, reverse the process. If it is not a NEW sensor, you're installing, put a little anti seize on the threads, only. It's easier than changing to oil.

RACE ON!!!

Just did mine. Piece of cake. I have a lift, so I had it easy. As noted, disconnect electrical lead, unscrew and replace. I did notice a slight increase in throttle response and a slight improvement in the idle.

when I did mine on an '85, it was suggested to me to 'warm' the car up a little to help with the removal of the old one. It was a long time ago, but I think I ran the car for about 1 minute. You don't want the exhaust pipe hot, that's for sure.

Thanks, everybody!
