Ok, I have had the truck miss a couple of times, both at light throttle, and it puffs a cloud of white smoke when this happens. Took the chip off, and also put in a new fuel filter as well, and it has happend again. Any ideas?? Injectors? Cp3?

 

Change the fuel filter if not done recently. Then run some injector cleaner through it. If your white smoke, rough idle stays I might get a leak check done on your injectors.

 

Thanks, I will get some cleaner asap! It idles just fine, drives fine, no smoke at startup, only when it misses. Almost like it runs out of fuel for a split second.
