engine rattle under load? 2500 rpm
I have noticed lately that my truck has a slight rattle knock type noise that you can hear right around 2500 rpm. My truck is a 5 speed 4.6 and only seems to mainly do it taking off in 2nd gear. It doesn't seem to do it in any of the other gears. I only have 129K on the truck. My truck is bone stock. I recently changed the spark plugs and cleaned throttle body and the egr ports. any ideas on what this noise maybe? Thanks
