Asked by Jul 26, 2017 at 06:31 PM about the 2000 Toyota 4Runner SR5 4WD

Question type: Maintenance & Repair

Hello, I have a 2000 4runner sr5 4wd. It's been
giving me trouble.  When I start the car it has a
high idle, then it proceeds to rev up and down. It
does it when I accelerate, i can watch the
tachometer stop then go until past 2k rpms and it
seems out. I have replaced the spark plugs and
wires. Cleaned the IAC and mass air flow sensor.
The throttle positioning sensor as well. I'm all out
of ideas and it's getting worse. Any thoughts?
