Okay, I raised the white flag faster than expected

Who knew effort would be required to change my O2 sensors. After jacking up the car, sliding under with proper tools/lighting I began to work. Clearances were so tight it reminded m of my Fiat X1/9. After much effort and fear of snapping off a sensor...and flashbacks to my college days...I gave up.

I now know why people install lifts in their garage. Until I get one, no more sliding around under 3000 pounds of car. I will gladly pay my nsx tech for this job.

Ah so you did have fun with O2s

Sometimes it require a torch gun to heat it up to loose it. I feel your pain

I was never able to remove my O2 sensors.
They are still in the oem manifolds.
Definitely a job for a shop.
