Well the new ICM made no difference. I don't know what to check next. I keep thinking about the fuel pump, but with 11 psi and the fact that it only acts up after sitting 45 minutes after driving doesn't make sense to me. Trying to think of a way to verify it. Maybe putting a potentiometer in place of the TPS and tricking the PCM into thinking the throttle is open more than it really is which should enrichen it. At least maybe I could confirm if it's a rich or lean condition causing this behavior. The scanner can't tell me because it's in open loop, so no fuel trims yet.
