hi I own a early 99 7.3 and have been having some engine trouble... last week the truck started chugging like it was running out of fuel slower and slower and finally shut off. I couldent get it to restart.. I was at 1/4 of a tank when it happened. well I changed the fuel pump, cleaned the fuel tank and lines, replaced the fuel filter, and cleaned the two screens inside the tank, and replaced the cps.. the truck now starts and runs but skips and jerks around 1500-2500 rpms, wot is good and idle is ok but rough... Ive run a few bottles of fuel cleaners in it since then but still acts the same.. the codes its pulling are p0475 (I have ebpv delete), 1316, 0344, 1212, 0340, 0470.. any ideas of what could be the cause of my problems??? thanks in advance. and happy new years!!

the truck has a new hpop, ipr, and icp. replaced 2-3 months ago runs the same with icp unplugged...

the 0470 code is the exhaust back pressure sensor try taking it off and cleaning the tube and sensor. what cps did you use? was it ford? if not go get one from for or international that's what the 0340 code is.
