If you want to really clean the sensor properly, they do make a MAF sensor cleaner for cars that makes 0 residue on the elements of it so they maintain their same functionality before and after. brake kleen carb and choke cleaner both leave some form of residue (though not much).

ok, lets start from the top then. For your EGR delete you have the valve unplugged, the cooler servo still plugged in and do you have the butterfly out? If the truck is bucking and romping around you may need to take that out or put it back in, it is really dependent on the flash that your truck has. Also it might not hurt to check your DPF sims out as well to make sure they still functioning as they are supposed to be.

did the dealer reflash your truck at all since you took the EGR off? you check the sims with a meter between the two terminals to verify that they are still XXXX ohms. The differential pressure sensor sim should have a set resistance, and the EGT sensors should probably be 330 ohms. Some of the early flashes required the butterfly to be removed, but the later ones still needed the plate in place for one reason or another. You may want to try reinstalling it just for shiggles if you don't know whether or not your dealer reflashed the truck.

if the sims aren't working it may be trying to do a regen for one reason or another. Usually regen is accompanied by a large plume of white smoke out the tail pipe, but not always. Then the truck tries a regen slide position and fuel injection timing and duration are all altered, most of which will cause bucking and surging. I'd ask around here to see if somebody has a throttle blade they removed to see if you could find one to reinstall just for a sanity check.

i have this lightning bolt problemo along with a ton of blue/white smoke. i got it after drivin through a terrential downpour last saturday night. gonna try the brakleen on the map. if i get the code free xrt will that fix it.
Sounds like your truck is trying to regen. White smoke is almost always the result of regen. Have you checked your sims to make sure you didn't get water in them? Or to make sure they are still intact? This is the most likely cause of an attempted regen.

depending on how your sims are made, if you made them or if you bought them. If you bought them I think it'd be pretty hard for water to get into them but I've seen some where guys just looped a resistor with no wire between the terminals, which is pretty scary to me anyway.
