My 2002 ford explorer for seems a bit sluggish. It doesn’t have that get up and go. Not sure what’s wrong. No check engine light is on. Gas is the same. Last tune-up around 2 years ago. Anyone have any idea what it might be? I changed the fuel filter 1 year ago, air filter is decent. Any suggestions are appreciated. It is a 4.0 L engine.

 

if you last tune up was 2 yrs ago, I would suspect a clogged air filter
