Gotta get a fuel psi gauge. It's the only way to know what's going on. I also have idle and hot start issues. My new gauge arrives tomorrow! There are a couple places to get them online. About $100. Also, smoke machine is best to find vacuum leaks. Lots of shops have them now. I found my throttle body was leaking and a bunch of other little places, too. Much more accurate than carb cleaner.
