The problem of my rough idling and poor starting, this whole time after replacing everything from the 02 sensor, TPS, IAC, EGR, the entire vacuum system redone, and countless other dollars... The Coolant Temp Sensor was my problem. Thanks to reading up on some other people's problems I decided to pop a new one in... It was actually a pain in the ***, but either way, I'm a happy guy with a very healthy iroc.
