Been trying to solve a hot start issue for years and finally have a starting point. The issue is when the engine is hot and you start it after letting it set for 15 mins or so it has a rough idle for 10-15 secs then clears up or dies. I discovered today that when this happens if you remove the vacuum hose that runs from the IAC to the fuel regulator it clears up. Any thoughts?
FYI 1995 RRC 3.9
