Ah, makes sense!

I will try again this weekend. Also noticed today that my throttle cable is starting to fray. I guess I will be looking for solutions for that next.

SUCCESS!!!! A pipe wrench, PB Blaster, let it run to heat up exhaust and it was still a B**ch to get out. Final tally is both O2 sensors, six plugs, wires, cap rotor and no CEL, and smooth idle. Have to see how my gas mileage is doing. Noticed a cable is fraying and thought it was the throttle cable and it's actually the kickdown (TV) cable. I guess that's next on the agenda.

Way to go man! And, yes, definitely get that cable replaced. You do not want to be stranded when it breaks.
