Tacoma Idle
« on: August 26, 2004, 02:15:46 PM »
I own a 2000 Tacoma reg cab :mad: when I am in first gear letting my truck idle along at about 800 rpms then all of a sudden it starts speeding up by its self up to 1500 rpms then back down. :mad: I was reading were the 2000 EFI systems there is nothing to adjust it is either that the fuel injectors could be dirty or malfunctioning? Experienced Toy mechs please help.

After you have checked for loose air intake fittings and/or vacume leaks--

The most common problem is a dirty/fouled air flow sensor that is sending a false signal. It is mounted on the air cleaner housing and secured by two screws.
Unplug the wiring harness, and then remove the sensor. I have had some success cleaning the sensor with brake clean and then lighty blowing it off with compressed air.

If all else fails, do it right and install a new sensor :driving:

After market, open element air cleaners are know for causing problems with the air flow sensor.
