Little info on the truck, 01 Dodge Ram, Cummins with approx 147K miles on it.
When it's cold out he starts the truck and it idles ok but if you attempt to raise the rpm at all it makes a horrible noise like a miss, blows crazy amounts of white smoke out the tail pipe. Holding it to the floor only gave 2200 RPM. Then it would drop down to about 1600RPM on it's own while still holding the go pedle to the floor. If you then let off the pedle and get back onto it it would raise rpm again and drop off. Seems weird for it to be hunting like that and not wanting to rev up.
After the truck warms up it seems to run OK.
Anyone got ideas? Exhaust rotted off so the only mods are a 4" cat back. It's a company plow truck.
Thanks.
