Question about Toyota Cars & Trucks
No year, no joy (3 generations and 3 base designs)
first off all modern cars there is no idle set.
that ended back in 1988 with carbs. USA, all my posts are for
USA Cars, if you are not USA< then now the time... to say so.
on EFI cars, the idle is controlled by the ECU at all times.
its one of its major hard jobs.
and is the last thing top work right on all EFI cars.
so, to work on any car, the first thing is to
open hood and find out which of 6 engines, it has.
that is first. after checking all fuses)
the 1999 is the first car, and all 1999+ here are OBD2 engines
and ECU controls idle. totally. at ALL times.
post the symptoms ???
1: what year?
2: what engine. there are many.
3: is the CEL , check engine glowing running
yes, then scan it, to see the DTC errors.
4: is idle to low, say RPM hot or cold engine.
5: is idle too high, say rpm ,hot or cold
6: is idle out of control , varies. hot?
why not post the symptoms and let us guide you on the correct path.

have someone pump the pedal and hold it, then you work from the right rear, left rear, right front, left front, while the person pumps and holds several times at each wheel.
