When i start my pickup in the morning it idles rough unless i rev it to 1500 rpms for about a minute. after that it runs smoother but occassionally has a miss in it. It has an airdog 150 w/ injectors that are 2 months old. I've noticed after i get on it and i slow down for a light or something it kind of misses quite a bit. It does it worse when i first start it. cold or hot. I was thinking maybe the fca or something but i'm not going to just throw parts at it. any help would be much appreciated.

 

Is it leaking any oil out the blow by? Did you put the injectors in yourself?
