idle surges between 1000-1500 RPMS. lack of power when engine is cold... turbo will spool up but the engine will not follow with it... its almost like the engine isnt getting fuel... how do i know if my Throttle position sensor is bad? or does it sound like something else? help!!
thanks

Is your engine lite on and how does in run when it at normal operating temp.

Enigne light is not on. Sometimes it idles fine, sometimes it doesn't. But it only surges when it is warmed up... Lack of power when cold, idle surges when warmed up...
