Idle surges after warm up. Has repaired computer, new ISC, temp sensor, 02, fuel pressure regulator, all sensors test with in spec. Timing is good. New plugs, cap & rotor, fuel filter all vacuum hoses replaced. Starts fine, when it reaches operating temp starts to surge, between 1100 rpm & 1900 rpm. If the ISC motor is disconnected it will continue to surge. NO CODES! HELP!
