Well as everyone has stated to check there plugs I did this weekend and found that all of mine were tight except for on which was #3 in passanger side but only about an 1/8 of a turn. Which leads me to the exhaust leak question that everyone is talking about, I have on Bassani Headers and there is a ticking sound coming from the driver side at idle? Now the truck has been to the dealer for the ticking sound (which i think is a rod bearning going bad, but good ol' ford has no idea so I'm waiting for an engineer) but after reading about this exhasut leak problem I'm wondering how could i be sure that in fact this is an exhaust leak problem? The only reason I don't think that it could be an exhaust leak is that people are only say that they are hearing the sound under load and mine is at idle.

Thanks

You would probably hear it at idle too.
