Hey guys i got a 99 dodge ram with the 5.9 144000 miles
And i just can not figure out my truck it ran fine I just did new distributor, cap and rotor new crank cam sensor new plugs wires new coil new aic new tps and map sensor. My fuel pressure is good i have good fuel volume as well.
Flex plate is not cracked. Been chasing this for a while now

My truck starts up but dies gotta keep hitting gas too keep it running and sometimes it wont even fire back up or wont start ittl kick back on starter and (yes it is timed right) but itll start great at times and wont start and then start hard
And when it decides to stay running after warmed up it dies going into gear

Maybe computer ? Need help i tried and replaced alot of things that could cause this i just am stumped. Thanks everyone

I don't know much but have you ever replaced the cat? I had a plugged cat once on a car that did the same thing. That's some miles!!!

So it was running fine and then the converter clogged? And it hasn't run good since O2 sensors were removed?

im not sure but i would bet if you put that o2 sensor back into the loop it will work it self out, with out it your computer is just making blind changes.

Right now since you have tried everything else I would try putting the O2 back on and see if it clears up. It is the easiest and cheapest route right now.

If I remember right the front O2 don't really matter but the back one HAS to be there and working.

I'm not knowledgeable with the 2G, but you need the front O2s to control the AFR. The rear sensor is for emissions. The first week may have been running on adaptive memory and then you made changes that reset the PCM and it now doesn't have any AFR input to run on. Usually in closed loop (warmed up) you need the O2s to run properly and it usually doesn't take a week to sour the tune.

weird,these trucks have the best engines ever built in my opinion...i have the same issues KINDA....when i am cruising and my truck gets down to low speeds it will just die on me or when i am switching from drive to reverse it will die on me,it's a vacuum leak is what i have wrong with mine,but i learned a little trick...when i am driving and my truck gets to the point where its gonna die,i just tap the gas and can come to a complete stop without it dying and she runs fine.runs fine in park as well (idling)
