Rattle in engine between 2-3k RPM
A month or so ago i noticed when i was accelerating that when i was between 2000 - 3000 RPM i could hear a rattle in the engine. I cant really explain the sound, except maybe marbles or something hitting each other. We have a 2002 explorer that has been doing the same thing for many years now, but no issues. Any ideas of what this is? Or is it very serious to get fixed? Any input would be greatly appreciated. The truck is a 04 4.0 ranger with 153,000 miles.
