Spark Knock - 05/4.6L
Is anyone else suffering from Spark Knock on the 2005 Supercab. The Dealership tells me "yes" you have a problem, but "no" we have no Service Bulletins or technical Service Specs to fix it, so "Tough" 
.
Problem that I am having, is when the engine is under accelleration it sounds like it is full of pea gravel. Its running on 87 octain, as the manual says, but now I'm being told that it needs to run on premium, but! if you burn out the valves its your fault. Hmmmmm.
Help!!!!!
