Whats the fuel pressure specs?
What's the fuel pressure supposed to read at idle? I hooked up my fuel pressure gauge to diagnose a harder to start/stumble issue and I read 61psi. My repair manual says 49 psi. That got me wondering if the fuel pressure regulator is faulty. I searched thru this forum and I only found 1 reference to fuel pressure and that post stated something like 59 psi+/-5.
#1 Whats the pressure supposed to be at idle?
#2 Anybody ever have the pressure regulator go bad?
Thanks to all.

I dont recall seeing pressure higher than 50, but I have only checked my 5.2L engine. for a hard start and stumble, I would clean the throttle body and also the IAC valve. (Idle Air Control) it's cheap to clean (carb cleaner and rags), doesn't take too long, and can't hurt.
