Question about 1989 Toyota Pickup SR5

Truck Idles weird?

I have a 89 Toyota pickup,3.0v6, 4x4.. And when it is in the idle position it revs up and down? When it is engaged into a forward or rev. motion it's as smooth as can be? Can't figure it out...

I would guess that a dirty throttle plate is your problem. If the throttle plate is not closing properly, the Throttle Position Sensor is not fully closed, with does not activate the "closed throttle switch". Remove the air tube from the intake manifold; and observe the throttle plate. if it is real dirty with black carbon build-up, this is your problem. Spray it with carb claners until it is nice and shiny.
Thanks for choosing FixYa for assistance.

Truck cranks great . idles great but when in gear and u take off at about 2000 rpm it bogs down as if out of gas , let off gass and it idles great again ! but it isnt the fuel filter.

Could be low fuel pressure, or a problem with the throttle position sensor or the mass air flow meter if equipped.
Could also be something with the EGR valve or a vac leak.

My 89 Toyota pickup idles too fast in cold weather

I would have a look at your coolant sensor, if it's reading the wrong temperature, it will cause a idle problem. If you can, get a scanner on it to verify it's operation.

1993 toyota 4x4 idle problem

sounds like your throttle positioning sensor is not set right so i would undo the two phillips heads that hold it and turn it till the idle doesnt fluctuate should be turned most of the way to the front of the truck. Also check your idle screw that throttle body could be set different.
