4.6 preignition

When is the last time your fuel filter was changed? I've experienced the same thing - sluggish and don't really want to rev as fast - and it was a clogged fuel filter.

4.6 preignition

It's not been too long 6K or so but the last time it was plugged... I changed the fuel pump shortly after so maybe it's worth a try. Thanks! I'll try to let you know!

Can you hear detonation, pre-ignition, in these motors?
