Idle control valve

Asked by Nov 08, 2016 at 10:55 AM about the 1996 Toyota Tacoma 2 Dr SR5 4WD Extended Cab SB

Question type: Maintenance & Repair

Is there any adjustments to this device?
My idle went up from 700 to 1700 for no
apparent reason.  Truck sat for about 3 months,
wtf?

If the truck sat outside check for rodent damage to vacuum lines etc. Mice sometimes chew through vacuum line causing leaks and odd engine behavior.

Thks bob, but a pair of stray cats kinda call under the truck home, at least at night. I have done extensive visual inspection, nothing.

It is always a good place to start. I have had to remove the engine appearance covers on my trucks cause mice get under them and eat the vacuum lines. You might try to disconnect and reconnect the battery to reset the ECU and see if that helps.
