lately I have noticed that when I get in my truck and start it up after it has sat in the yard for a couple of days it will idle rough and blow white smoke for about 20 to 30 sec until it warms up and then all is fine. well this morning I got in my truck and tried to start it up and i turns over but wont fire up. it almost started 2 different times but even when it did that it was really rough and it only idled for about 5 sec. and that is it. I checked and dont have any codes I took the smarty off and still no help. I do still have a quadzilla on there but it is turned off. I checked all the connections and they are good. It has only been about 1500 miles since I last changed my fuel filter and oil. I dont know where to start, the truck only has 21k miles on it.

 

Maybe some bad fuel clogging the filter??

 

There is a flash update for your Engine Control Module (ECM) to reduce white smoke Refer to TSB 18-041-05 on your visit to Dodge dealership.
