Quoting keydiver:
Yes, that's the first thing to check. The ECU closes the FPR solenoid for the first 3 minutes after a hot start, to help with vapor lock/fuel percolation issues. Even with the solenoid working you may have issues. Our cars run extremely hot under the hood, and when you stop moving all the heat really soaks everything in there.
So what's the remedy for this issue, if any? I've got a good IAC and the BISS is set fine. For the most part, the car idles at 800rpm like a rock, but shut it off in a parking lot, come back out five, ten minutes later, and the idle drops to 500 or less and, in some instances, dies. Really annoying.
Could the FPR solenoid be opened up or eliminated? Pros and cons to elimination if even possible.
I'd been thinking about posting this very question recently, but was going to do some research first. /ubbthreads/images/graemlins/smile.gif
