hey guys, so im having a little problem. When i start the truck up it idles nice and smooth at 900-1000 rpms and at 34ish psi fuel pressure. After idling for a bit it drops to about 800 rpms, runs rough and very rich and fuel pressure jumps to about 40 psi. this also happens when im driving around and am sitting at a stop light for too long. I bought the bronco2 with the 5.0 already swapped it in and it has been doing it since i got it, but now its getting worse and has died on me a couple times when it makes that switch in pressures.
also when i rev the engine fuel pressure drops to 30ish psi.
thanks, dylan
