I'm guessing he put it in the Dodge section because it was acting like a Dodge.
It's in the right place now, though.
I agree with Kursed.
The only way to fix something like this is to hunt it down the way you're doing.
OBD code 33 indicates that the Mass Air Flow sensor is reporting more air is entering the engine than makes sense based on RPM and TPS.
Codes 81 and 82 are for the 2-3 and 1-2 shift solenoids... Indicating that they either stayed on or off after they were told to change states.
Whatever caused the van to die backing out of your driveway likely set that 33.
The 81 and 82 are probably due to whatever short was blowing the transmission fuse.
I don't know what else to say about it.
I once found an abraded wire that was causing a random misfire code on a 1996 Camaro (Code read as failed camshaft position sensor).
I found a wire shorting to the inner door skin on a 1994 F-150 that was causing ghost locks.
But in your case, since the problems aren't as isolated, it might be harder to find the problem.
I have seen some vehicles act pretty crazy when they've got an issue with a ground strap or battery ground.
That can cause the computer to get all kinds of ghosts.
