I have a 2001 F150 supercab with the 5.4 engine I have noticed in the last few days that when you give it the gas to speed up that the engine makes a noise like the lifters are rattling, kind of like a spark knock the truck has about 58,000 miles and I have never had the plugs changed. I have cleaned the injectors in the past with Seafoam. Does anyone have any words of wisdom to offer?
Thanks
Keith

 

I would Make Sure all the spark plugs are torked to spec.

Welcome ! Did this noise follow a gas fill up? Do you buy gas at random stations or the same one? You might try a different station at the next fill up and see if it's still there before you start replacing parts.
