Yes I took advice and read about searching threads 1st . Still not finding what I'm looking for . What I've read I'm sure plenum is a problem & cause of other problems. Think my 99 has a 94 motor in it # is 53006714 - 31827 also casting date 4-12-94 . Motor has egr (99) did not it also had transducer before 1 of 3 mechanics over 8 months has lost ! With no fix and out without a truck running good enough to pull it over an any hill I come here for some Dodge Guru Knowledge !!! Need to fix asap

 

sounds like you do have a 94 motor because only up til 95 i believe was there egr. as far as not having power your plenum is probably blown, it happens to all of them once its blown it clogs your cat and ruins your o2 sensor. a clogged cat would cause it to not have alot of power

 

Has NO Power at all ! Tried driving down the road and foot to the floor it wouldn't get 20mph It surges at idle , bucks , jumps when in gear. Getting codes for tps , cam , crank , O2, misfire almost everything . Changed every sensor except O2 . Brake booster hose come off once when reached across and motor idle quickly leveled out . Think I have multiple problems.

 

Sounds that way. Remove the front O2 sensor from the exhaust, see if the truck runs any better.
