High idle speed

4cyl with performance header and throttle body spacer.... High idle speed 1700 + or - a couple hundred. Won't settle down.
How do I get it to cooperate and what should the idle speed be for a 4cyl?

Every time i start my car it sounds like the revs are high then settles to normal revs what is causing this


If the idle speed is above 2000 RPM then drops down to normal, the common cause is a faulty idle air control valve or a dirty throttle body.

Hi i have a code reading P0506 for a 06 GMC Envoy XL any recomondations


{: ) DTC P0506 Idle Speed Low
The usual cause is an excessive carbon build-up on the throttle body. If this is the case, I suggest you have your throttle body cleaned and perform an idle relearn procedure using a GM scan tool. The idle relearn or reset procedure is very important, otherwise this code may still remain even after a throttle body clean.
In a similar fashion, if the ECM/PCM (engine control module) of a high mileage vehicle is replaced and/or reprogrammed without performing the Throttle/Idle Learn procedure, the ECM/PCM may no longer compensate for existing carbon build up in the throttle body, causing it to return with a similar concern as well as DTCs P0121, P0506, and/or P0507.
There are other conditions that can also affect or reduce idle speed by increasing engine load like incorrect torque converter clutch (TCC) operation, accessories that require additional torque to operate, restricted exhaust, and mechanical conditions that limit engine speed.

1997 chevy want alot of horsepower and speed


Just a note, if this is an unaltered system, it should contain a sequential fuel injection system, which does not use a conventional throttle body. It uses a spider system instead, which is much different than the pre 1996 models.

Engine revving itself.


some times when you put performance parts you have to adjust the gas flow to the engine and check you IDLE CONTROL VALVE that would cause reving on your car and your friends car also
