Howdy, im kinda new to this whole honda tuner thing. But i got a problem. I purchased a 92 honda prelude SI (2.3L Non vtec, 5 speed) The guy that had it put a nice exaust system and an AEM cold air intake on it. Real nice and all but the guy apparently wasnt very sharp. He threw the IACV and the intake charge temp sensor in the garbage. Now the car idles alright when the weather is above 75F (i live in florida) but as soon as the weather is cool, the idle jumps from 2000-3000 RPM CONSTANTLY. About every second it humps. Annoying and embarrasing. The colder it gets the higher the idle jumps up and down. This happens with the engine hot or cold. As soon as you start it in cold weather. I put a new Air charge temp sensor on, no differance. Any input would be appreciated. William
