Hi all--Chasing a P0125 on my 1996 LX 450. It was intermittent, then the other week it became permanent and the truck started to run very rich (by smell), rough, missing, etc. Checked upstream O2, found signal wire hanging by a corroded thread, replaced the harness side connector.
Started it up, ran worse than before, but no engine light nor any stored codes any longer. Reading the posts here, I disconnected the battery for an hour or so to trigger a re-learn. Still runs like crap after a couple starts, missing, short-term fuel trim at -19% or so, etc.
I checked the data stream coming from the TPS and it is at about 24% at idle, which is obviously out of spec. Should I expect this during a re-learn? Should I adjust now or wait until I (try to) drive it a bit so the ECU can catch up? Throttle does not seem sticky. Did not check for carbon in the throttle body yet, but mainly wondering at the moment if I should be expecting the TPS values to be unreliable during re-learn.
Thanks for any insight.
