03 Dodge Durango R/T Rough Start Problem
I am new to the Dodge forum and am not a car guy, so please forgive me if I sound uneducated when describing my problem.
I have a 2003 Dodge Durango with 118,000 miles on it and have been having problems with a really rough idle when its started from a cold start. When I start the car first thing in the morning, or after it has sat for more then an hour, the car will start normally, rev to about 1000 - 1100 RPM, then slowly migrate down to 600 RPM in a few minutes. After those first 3 - 5 minutes of running normally the truck starts to struggle and the rpm's will start to dip to between 300 - 500 rpm and it seems as though the truck is going to die. The muffler will start puffing and a distint oil/gas smell will come from the muffler. If I leave it alone for another 2 - 3 minutes the truck will suddenly and by itself rev the engine to 1100 RPM and then idle normally at 600 RPM after that. After that rev to 1100 RPM I can drive the truck withouth problems, however, if I try to drive while the engine is idling roughly or try to just start the truck and go I can press the gas peddle down and nothing will happen for a second and then a bang will happen.

believe it or not a bad battery can cause the truck to not run right at idle, the higher revs (1100 rpm) could be putting just enough charge back into the battery to right the issue and then it is fine until you shut it off again. (yes the battery can be bad and still have plenty of juice to turn the engine over, average life is 4 years in these trucks)
