At idle my truck run rough as well as driving, i had a friend change 2 of the spark plugs after he used a hand held diano which told (from the codes) that 3 and 4 are not firing properly. 1)why does my truck fell as if it about to stall. 2) should all spark plugs be changed. 3) why do i smell burnt fuel when i get out of the truck
