I have change the following: Idling valve, TPS sensor, injector rail, MAP sensor, intake, throttle body.

Please help me!

Hi,

Have you checked for engine vacuum leaks? That can be a common cause. Also, is the mileage you listed correct?

Here is a link that explains how to check for leaks:

Also, when you first start the engine, will it continue to run at idle?

Let me know.
