Every now and then, when coming to a stop, truck going to idle, I will get a "miss" type of scenario. I would pop her into neutral, blip the throttle and then the "miss will go away. Last night, I started her up (30 F) and got the "miss". I blipped the throttle and the "miss" subsided but not completely and the L was running rough. Also, when I revved her up, there was a "miss at/around 2500-2700 RPM. This morning, no problem. What gives?? The dealer checked for codes and said there was nothing showing up (last week). This happened before and the dealer could not find any codes bot said a couple of injectors were sticking. Flushed the injectors 2x before the sticking would clear. Now, I also find that my gas milage has gone down after the cleaning. Any help would be GREATLY appreciated!
Sorry for the long post.

 

My bet is on the plugs. If they're stock I would check to see if any are loose, or better yet, change them.

 

How many miles on the truck?

It might be a good idea to change the fuel filter

 

Excessive oil in the throttle body area causing burnt carbon build-up around the edges of the plates?

Dirty(carbonized) IAC(intake air control)?

Clogged PCV valve?

Vacuum leak?
