Hey guys my brother 4.6 was hessitating because water got in the coils with the spark plugs. The truck is a expedition 2000 i changed the spark plugs except one that I could not change. Now the truck is hessitating but very little compared to before the old spark plugs were gaped like .61 and the biggest suppose to be .56. Can the hessitation be that one spark plug or maybe a coil in not connected right what do you guys think thanks lmk.

Hey guys can the problem be a coil that is not connected correctly or the old plug sometimes it hesitates a little but sometimes a little more. It hessitates around 1000-1600 rpm and not much thanks lmk.

i would try taking the boots off the coils and blowing them out, then seeing if it still does, theres also a chance that all the water shorted out a coil as well . is a there a mil light on?

What do you mean by "flood" was the motor submerged or were you guys just washing the engine bay and got water in the plug holes?
