hi guys my evo IV idle's at very unusual levels. It sits at 900 rpm but then can idle up to 2000rpm , it seems to sit there for a while and can range from between 1500- 2000 rising and dropping and will then eventually go back to 900. is this the ISCV. i can hear clicking from the electrical connection block when the ignition is on but the engine off. but i am struggling to remove the connector to check the pins. should that clicking be apparant??? or do i need to continue to try and get the connector off, just dont wanna force it. Finally any idea's on what else it could be or where is best to purchase a new one?? thanks guys
