2000 Dodge Ram 5.9(360) running rough

Asked by BoostedGS Jul 30, 2014 at 05:45 PM about the 2000 Dodge RAM 1500 SLT Quad Cab RWD

Question type: Maintenance & Repair

Have a 2000 Dodge Ram 1500 2wd with 5.9(360). Replaced within the last 100 miles
Cap, Rotor, Coil, Plugs, Wires, TPS, MAP and IAC. Trucks feels like its misfiring from
time to time and hesitation in the throttle. It backfires occasionally. Fuel pressure sits
at 50 psi while idling. If I start it and let it just idle after a couple minutes it will start
sucking lots of air like its starving and the engine dies out sometime, other times it
picks itself back up to normal and its fine. When it does the sucking and dying part it
still holds 50 psi for fuel pressure. I'm at a loss on what to do next, any ideas?
