got a itr swap. with chipped p28. my coolant gauge from the inside acts weird. when i stick the key in, not to start but where all the lights turn on in the cluster. the temp gauges goes all the way up. but when i start it goes all the way down. after the car warms up the temp gauges never moves and it stays down, all the way down it doesn't move at all. anybody know whats wrong with that. i have no check engine light and im getting a high idle at 1500 when car is warm and at cold, like 2500. already cleaned both fitv and iacv.. my brakes are leaking somewhere too... could that also be why my car is idling? what could this be?
