I have an 06 dodge cummins when it idle it has a stutter but only on idle

 

When I had a failing injector mine had a lope and somebody said clean your map senator plug-in and pull it out and clean the sensor, it helped with smoke a little bit but it fixed my lope

 

I'll try that thanks

 

if that doesnt fix it you could clean it out with some seafoam, or i use atf dexron. the atf works really and i put one qt in a tank to clean. i did that for 3 tanks and its good as new. lots of peope say not to run atf through system but a number of guys do and have had good results with it, 200,000+ miles on stock injectors.
