Ok, so I start the car and when its cold it has a normal idle. after the car warms up, the idle sits at 2k. Has anyone else had this issue? How do I fix it?

 

iacv

 

Try this

Start the car and take it for a spin until it is completely warmed up.
Turn the car off and disconnect the negative battery terminal for about 2 min to reset the ecu.Reconnect the battery terminal and start the car.
Now since your engine is warm the idle should settle right away.
Take a screwdriver and adjust the biss screw that is located on top off your throttle body(you can see it between the "legs" of the strut bar).
Adjust this until you reach the desired rpm and then let the car idle for 10 min.
Turn the car off and back on and see if this fixes the problem.

 

This is not recommended since it throws off the iacv. If you touch that biss screw you will need to re-tune.

 

Adjusting the BISS screw as mentioned above is BAD ADVICE. You should not adjust the BISS screw unless you have initiated the actuator within EvoScan or the factory MUT II or III. If you don't know how to do this then leave that alone for the time being.

I'd check the simple stuff like vacuum/boost leak, clean the throttle body and ensure your cooling system is properly bled (this can cause funky stuff if coolant isn't reaching certain temp sensors).

I have checked all the vacuum lines and they are good. The coolant idea isn't bad though, I will flush my system and clean my throttle body and see if that helps.

 

Try adjusting the tps

 

Can you log in evoscan? If so it should tell you what your TPS is set at...that will help. You can also test your IACV if you want by unscrewing it from the throttle body with the car off and leaving the electrical plug connected. Pull it out, make sure the O-ring is in good shape. While holding it have someone turn the car to on, watch the IACV and make sure it moves in and out and clicks, if so it should be good, if not, it's bad

 

tell me what fixes the problem cause im having simular problems.

 

Well, got the iacv ordered. Took my off and it doesn't move at all when I turn the key over. Can anyone tell me how to adjust the tps just in case this doesn't work?

 

if you don't mind me asking , from where you ordered? I believe i might have to order one too.
Thanks

 

You will still need Evoscan or a MUT tool to adjust the ICV as already posted above. Easy to see if the ICV is working correctly with a quick log, just see if it's between 20 and 50 steps on warm idle.
To set the TPS, the output voltage should be 0.68v to 0.72v base setting with the ignition on.

I have evoscan. Waiting on my tatrix cable to come in.
