would a broken ring or blown intake gasket cause the truck to stumble on aceleration and backfire when i stomp the gas from a dead stop? Also the truck will randomly stop smoking at idle and one time someone told me to unplug the egr vaccum line, plug it, and drive the truck to see if the egr was bad and when i tried it the truck did not smoke for at least 5-7 minutes and then out of the blue started smoking again???? Maybe it is haunted LOL!!!
