Got under the FX45 last week hoping to remove and replace the bank 2 #2 oxygen sensor. Couldn't do it. Previous owner rounded off the nut just for me.
So I gave up, but before I reconnected the plugs I sprayed both with DeOxit.
Several drives later and no check engine light.
Normally the light would pop on the second drive after I cleared the memory.
So far so good.
DeoxIT is magic in a can.
