Why would my diesel 2003 Dodge Ram 2500 start blowing black smoke

Asked by Aug 27, 2015 at 02:01 AM about the 2003 Dodge Ram 2500 Laramie Quad Cab LB 4WD

Question type: Maintenance & Repair

I had injectors changed a few months ago. Could this be fault injector.  Or is this
a air leakage or combustion poblem.   Also it stalls sometimes whe I apply
brakes at stop sign.   Seems to lack power.  This smoke only blows when I am
accelerating.  Please help sis I live in country.

Black smoke means too much fuel going into the combustion chamber and not getting burned- this will take a mechanic to fix- but my advice is: dump the dodge and get a new truck- in fact, check with your closest dodge dealer, your truck may be part of the buy back program because of dangerous steering design-


One cause may be a clogged air filter.

Thanks for trying to sole this black smoke issue guys. We did find problem to bolts where loose on heater. tightened them and then ran at high speed for a bit. that cleared all the old black out. Now running great and lots of power. thanks so much. Much appreciated your site and help.
