2004 3500 Express Speedometer/shifting/ABS issue
Hello,
First post here, but not new to the whole forum deal. Anyway, I'm trying to help my old man diagnose some issues with his work van and they've got us both stumped. The van is a 2004 3500 Express with the 6.0 motor. Its got 320,000 miles on (as far as we know) the original drive train. Ran fairly well up until a week or so ago. The ABS light started coming on, the speedometer was very sporadic, and it wouldn't run through shift through all the gears. Also seemed to have a loss of power. Did a little research, and ended up replacing both front ABS sensors and the VSS along with a few other maintenance things (drivers side ball joints and passenger side hub assembly). Didn't seem to make any difference, and we're not sure where to go next. Should we try replacing the rear ABS sensors? Any other ideas on what could cause these symptoms? GEM issue? Transmission issue? Some other obscure sensor that I don't know of?

It is throwing a pair of codes. I don't recall the numbers off the top of my head, but one was a fuel delivery issue and the other was an emissions issue. The result was a misfire at idle. It was throwing these codes before this latest round of symptoms appeared, although I spose that doesn't mean they are unrelated.

Sorry it took so long to get back to this. Hooked the can back up to a code reader tonight and got a laundry list of codes; P0200 Injector circuit (X2), P0300 random misfire detected (X2), P0455 EVAP system leak detected (X2), and a P0449 EVAP system vent control circuit intermittent.
Also drove the the van a bit tonight. Has noticeable misfire, but most concerning symptoms are the erratic speedometer, not shifting past 3rd gear, and the random ABS pulsating. ABS and brake lights come on and off while driving
