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.
