 Subject: 1995 Dodge Van w/318 sluggish backfire

Hi all,
I know this isn't a Dakota, but I'm thinking that's where the motor in my van came from.
About the Van:
1995 Dodge B250 Conversion Van (2 wheel drive)
318 from a junkyard (I can tell by the small logo tags they put on the back of the heads, year unkown)
Fuel Injected.
I just got this about a month ago
Here's what's been done so far
When i test drove it, it seemed to run fine, but had a bad exhaust leak
I pulled the doghouse off, a bolt was missing from the exhaust manifold, i put a new one in, fixing 95% of the leaking exhaust (small tick now, gasket prob got abit messed up from running without a bolt)
The tranny slips between 2nd and 3rd, it seems to shift way too early. It seemed to shift better when I was on the gas more, but also would backfire.
We drove about 200 highway miles, the last 15 i noticed that it was sluggish during acceleration.
I changed out the plugs, all where about the same level, normal and all plugs looked to be in the same condition. I got some new ones installed.
Idle seemed to improve, sluggishness was still there.
I checked for codes using the key on, off, on, off, on off method.. only code listed was the one that it was done displaying codes, so basically no codes exsist.
The plug wires look new as well as the cap, i didn't pull it off yet to check the rotor.
I replaced the coil and the MAF (or whatever it's called, it's on the front of the throttle body with a small hose and two bolts. I noticed build up under the throttle body (when looking down the blades), i cleaned up what I could without a teardown.
No change, it still sluggish and backfires under acceleration. There is some valvetrain noise, but nothing that I would consider excessive. Oil needs changed out, but is full and it doesn't smoke at all and doesn't seem to be burning it.
Timing? Fuel pump? O2 sensor (shouldn't that throw a code)?
Any ideas of where to look or what to do would be great, I have to get this thing running ASAP to move.
Thanks!
Jim
