'95 LT1 miss-fire Hey guy's, thanks for all the support all of you offer, I certainly appreciate it. This is a continuation of my last post... at this point i have changed the PTS sensor, and finally purchased a fuel pressure gauge that reads about 38psi as a norm, however, the pressure will pulse to about 42psi (and i do mean pulse) when i raise the idle to about 1500 rpm (what i mean as pulse, is that it will go to 42 for about a half-second then back down to 38). Now when i turn the ignition to the run position it will go to about 42 for a second then down to 38psi. Now, at rest with the ignition off, the pressure sits at maybe 10 or less psi... should the line have pressure all the time, because when i installed or removed my gauge there was no fuel escape from the valve as if it didn't have pressure in the line... anyway, thanks again!
