so I replaced my right side lower valve cover gasket .....along with that I also replaced the fuel filter while I had it off....got it all put back together ...primed the system and fired it up....let it idle for 10 min or so and took off down the road ... as soon as I got in the gas it stumbled and cut off????...it started right back up so I took off again and all was fine until I slowly eased down on the pedal and it started stumbling again?....came back checked it with the tech 2 and had a P1093 but no engine light ....I then went down the road with the tech 2 hooked up and took a snapshot and when I get on it the rail pressure drops almost to nothing?????
so obviously it was running just fine before I replaced the gasket?...any idea what this could be????...it's got me stumped...could there possibly be air still in the system ????????
