Idle issues

i have a 1995 tacoma 4x4 3.4 the idle when you first start is around 2200 rpm and when it warms up it drops down to about 1400- 1600.. ive replaced the iacv and and all new vacum hoses and cleaned the throttle body still no change.... Any ideas?

 

loose or cracked vacuum lines.

the idle speed adjustments are a "fixed" setting "tamper" marked with yellow paint, so unless you have reason to believe someone tampered with them, its going to be a vacuum leak causing high idle

 

It's not the vacuum lines I replaced all of them new and have even rechecked them to make sure they are right

 

It's a manual transmission and the iacv is new... Everyone I talk to says it's the computer I just find that hard to believe.. I've looked for a new throttle body thinking it's that but can't find one anywhere... I don't want to spend 400 on a computer and that not fix it.. the iacv made the idle start to jump when coming to a stop when I put the new one on...

 

It's fixed now I had to cap off a vacuum hose that runs to the ac that new engine I installed didn't have Thrace valve and never noticed it...

 

What hose? I had this problem for a year and just fixed it ...combo between iac and tb...installing a new engine right now too

 

Did you try resetting ECU? Pull ECU fuse or disconnect battery for a bit. Let it idle after reinstalling for 15-20 minutes and see if that helps.

 

he said its fixed

it was a vacuum leak
