Wtf
Yesterday I replaced the 02 sensor-threw a code, thought I would clear it, disconnected battery. No codes. Car really seemed crispier, like better throttle response. This morning after I left my office WTF! car (87 auto) didn't want to upshift normally. From 1st to 2nd slower shift-but hard shift-2nd to 3rd takes to long, but hard shift-didn't shift into OD. Is this just coincidence or what? Much help would be appreciated. Thanks in advance.

I cant think of any connection between O2 sensor and shifting. You didn't accidently lean on or stretch or disconnect your throttle body valve downshift cable did you? I know that usually only affects down shift to passing gears but I'm just trying to think. hmmmmm..I dunno..does 87 have an upshift relay? 90 has one mounted on fender well beside the AC control relay near the brake master and battery where the fan relay was on my 84. Well, I'm not much help but I gave ya a bump..good luck.
Oh yeah, thanks for the bump
