Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you are getting black smoke it is because there is some fuel not burning off. I would do a compression test first just to verify that the engine is fine. It is common for this engine to have valve seat issues. If that is fine then the signals from the oxygen sensors need to be checked. This would tell you if there is a bad sensor or I would use the fuel trim readings to see which side of the engine is doing this as it can be a vacuum leak or leaking injector. I hope this helps. Let me know if you need anything else.
