Hello all, first post on here, I own a 1990 production date mx-6 and ever since I saved it from the junkyard I've been having a weird problem. When I start the car it jumps to like 2500rpm and stays there until the car warms up. It used to stay high but I adjusted the idle screw down to the factory recommended 750 rpm, I guess some monkey was futzing with the carb before me. The funny thing is when I start the car when it's already hot, or if it was like yesterday and the sun made it 102° inside the engine compartment it doesn't do it. Any help? I assume there's some cold start temperature sensor somewhere that's broken but I have no idea where to look for it.
