Question about Toyota Cars & Trucks
Played with the throttle position senor cant find a happy medium there. want to change the o2 sensor but cant get the nuts off as somebody has striped the corners off them and there in such a tight stop cant get anything on them
No car stated, no engine, and no year.wow. that is hard.
guessing, i see.
no year car stated
no engine option, which engine.?
what country.>? USA, Flordia.
why not get it serviced?
why not use a scan tool (1996+) and see if there are stored or live
DTC errors. (tops list)
a technician can tell you if the engine lacks power or the trans is failing.
The transmission will never use OD if the engine lacks power.
or the transmission or engine are stuck on limphome mode.
The TPS most be calibrated, ever seen the FSM book
the factory service manual> if set wrong idle speeds will wrong.
that which is stripped is bad, replace object stripped, the TB.?
the "Throttle body" or re-tap it or heli-coil it.
Test 1: done i 3 seconds flat
see FSM , see Trans, chapter.
see the stall tests. does that pass, parked, hot engine.?
that be first. if not , we work that first.
stall rpm too low, bad engine.
stall rpm too high , bad tranny.
i never once said to replace a part, that be last. (after diagnosis)
tell more get more.

My problem was solved when I repaired my 4 wd activation dash switch. The switch was contacting on 2WD & 4HI at the same time. The front differential activation is vacuum activated possibly creating a tug of war that didn't actually engage it but drained off vacuum from the engine? A theory at best but stumbbled across it because I knew the switch wasn't working properly I repaired it and low and behold rough idle disappeared and all is good for 3 weeks running.

Sounds like you need the updated engine computer for harsh shifting. Look up under the glove box at the computer. Number should be 89661-02K21 if not, you need the update. It is an 8/80 warranty item.

SOURCE: transmission wont shift
check the kickdown/throttle valve cable. It may be bound up and stuck in the maximum position giving you extremely late shifts.
There ISN"T any modulators or vac lines on any Chrysler automatics
