*Smacks head*
Of course! I forgot to pull the muffler off! Fer sure I'll do that before anything else!
L O L You know I'm kidding.
I lift up on the accelerator at 42 mph and therefore force O.D. and converter lockup from that speed on up. I don't think I could lug it a whole lot more if it had a stick.
I guess O2 performance can slowly degrade over time, not just work and then suddenly fail. Engine sure runs nice, no missing, no smoke, no flat spots, no CELs, good power, etc.. I just haven't found the magic formula yet.
Maybe there's a pill I can put in the tank???
P.S. No emissions testing here.
