OK yesterday my truck started idling weired so here's what it does when you start the truck it idles fine but after a while it starts idling low and it dies sometimes

 

without much else to go on, sounds like the AAV under the throttle body is sticking.

 

im a newbie what is avv how do i fix it

 

I have the same exact problem with my '91 toyota 4x4 pickup. i think it has somethin to do with adjusting the idling but i have no clue how to do that. i think you have to have a special wrench because i have nothing that i can fit up in there. please help!

 

theres a screw on the throttle body that u turn to adjust the idle. you need a flathead to turn it

 

if i do adjust witch a was about to but i was afraid it would make it worse would it fix it for sure

 

Nobody can say if it's 100% going to fix it, but I'd say it's a good place to start.

 

ok where should my truck idle at rpm?
