Background: I've got a problem with my 2006 Ram 3500 Mega Cab. The truck is over 5 years old and has 68K. After having used a Smarty Jr for over 1 1/2 years, with not one issue, I get my first CEL and loose power and it has a miss which seams like an injector issue while cruising in overdrive at 70 mph. It limps back into town and I get the codes read. The codes are 204, 209, and 2149. The next morning I revert the program back to stock and see an immediate improve meant but still have CEL so I take it to where I bought it to have service check it out. They tell me that I need number 4 injector replaced (p0204). I say thanks for the information but that I will think about it. Driving it home I noticed that it seems to run fine and that I no longer have a CEL So, my question is do I have an injector issue that was brought out by using the Smarty Jr?
