I have an 03 evo and my idle is real sluggish and almost cuts off when car is cold, but when it warms up it's ok I replaces the tps yesterday and it fixed the problem I was haveing with the idle sticking at a certain rpm an wouldn't come down and that's when the throttle cable is all the up I still cnt set it back to factory standards cause it Boggs out . I've tried everything looked for leaks just cnt find anything , I have replaced the tps an that is all I thought it might idle air control sensor but I Dnt I'm kinda wasting money tryin to figure this crap out so, maybe u guys cnt help me thxs..
