High Idle On Startup

[jackrose01]

What are the possible causes, a high idle speed motor hand was cold? I assume this may be leaking from somewhere, because once the motor to idle is normal and temporary, but I am trying to figure out where the leak is probably because I do not like to use sealants unless absolutely necessary. Any help is appreciated!

i think the o ring was a bit loose, so i tightened that up

when i started the car up without the plug at the bottom of the tps plugged in, it idled at 1500 or so, when i plugged in it went to normal, and then i unplugged while the car was running and the car stalled

does this all sound like normal behavior?

did you follow this guide on cleaning the aac valve and setting the idle? it sounds like your aac valve idle adjustment screw isnt set right.

If you did follow these steps (unplugging tps let engine get to operating temp etc) disregard.

I did the aac valve clean ages ago and thought i followed every step but for shits and giggles went over my whole car and got to the ecu and found i had adjusted idle there way too high and the aac valve way too low. Strange that i did this but there you have it.

Re did the idle setting steps and my start up and idle is way better and after revving returns to idle quickly and smoothly.

Yeah.
