ok after like a month im still wondering why my car doesnt have high idle when it warms up it has a low idle like the motor even shakes at idle in the morning and when i smash out and come to a stop it dies out so what could be the problem?

 

..

 

What did you swap on?
Thinking you may have done a Y8 intake manifold which doesn't have a sensor to bump up the idle when cold- just trying to make sure.

 

im running si intake manifold could it be the EACV valve?

 

Maybe you just need to adjust the idle screw on the throttle body. No more than 2 and a half turns counterclockwise from the fully seated(clockwise) position . If the Throttle Position Sensor was moved during swap then maybe it is now out of adjustment. Just a few ideas good luck.

 

thankx i will try that but the idle screw is rite under the the throttle body right correct?
