Default truck dies when i take my foot off the gas

i had to change my selonoid for my plow today and when i hooked the battery back up, the truck will start but as soon as i take my foot off the gas it will die out, there are no codes coming up. i dont see anything from the plow that would affect the truck at all. Its a 2000 dakota 4x4 3.9 liter.

Sounds like your TPS may be going out BUT FIRST reset your ECM, disconnect the battery turn the key to start and hold for 10 seconds or so let truck sit for 10 min with no battery connected. Reconnect battery, start truck let run for 10 min shut off turn on let run for 10 min shut off turn on go drive, don't get on it just a nice 10 min cruse this should help, if not check your TPS (Throttle Position sensor) with a meeter.

you may ned to upgrade your battery also. if there is not sufficient voltage going the the pcm it will shut down. its not like the old days were if you disconnected the battery the alternator would keep truck running.

Dead or dying alternator or battery. Ignition components could be also beshot. Has it been a while since your last tune up?

take off the TB and clean it... yank the IAC off the TB and clean it. if this doesnt fix it, your IAC may be dead or dying.

mine did this not too long ago and all i did was cleaned the battery terminals
i know you said you had yours off ,but just try cleaning them and reinstalling

but remeber once power is taken away from the computer it will need to relearn or reset itself may take alittle to get it back too normal
worth a try anyway

i had this problem with my 98 dakota 3.9 no plow or anything all i did was take out the idler moter from the air intake and clean it, $$ is a little tight for me, but a new unit should only cost like $50 at your local auto store, but take the old one out and see what it looks like, mine had a covering of carbon on it while a new one would be almost the same color as brass see if this helps. BTW my truck also would not start sometimes without hitting the gas, let me know if that works
