So I did all the main problem checks: cleaned the air filter and put a new IAC on and it still rough idles and dies sometimes idling or when the clutch is engaged. Does anyone have any idea on what else it may be? It has a BBK cold air with BBK filter and BBK 70mm throttle body along with BBK full length headers to mid pipe to two chambers. If anyone knows how to correct this problem, I'd appreciate it. Getting tired of having to constantly start my car.
