Today we fix the very high idle in our 1996 Toyota 4Runner. One these it is very common to find a clogged up and dirty IAC Idle Air Control Valve on the throttle body of the 3.4 5VZ-FE. Problem occurs in all Tacoma, 4Runners, T100s, and Tundras with the 3.4L engine, and process to repair is essentially the same.

Sea-foam.
Pour sea foam in the iacv tube then turn on.
Had to resort to this cheap fix when I couldn't get the JIS screws.
Cleared my code! Idles smooth as..
Those screws suck.
Whew.. that burns cuts.. that means its working lol
This isnprobly why mine idles weird on cold start I should check
I cleaned my iac and know it's too low rpm at cold Start haha any suggestion ?
Oh sheet !!!! It’s Sunday ?!?
Where did the weekend go ?
Another thing fixed! Next week the 4wd issue? Curious what's wrong with that. Keep up the great work!
Those screws are JIS, not Phillips, and that’s why they are dangerously prone to rounding out. Use a hammer on a Phillips screw driver or an impact driver (one that you actually whack with a hammer as you turn)
What’s the normal idle when cold start?
You should get yourself an ultrasonic cleaner. You can pick them up cheap at harbor freight or in Canada princess auto. Or off slamazon dirt cheap
