Sluggish accelerration

Yeah, it sounds like your clutch needs replacing. It does take skill and nohow to do it if this is your first time. I would buy a repair book for your car and read it over and then decide if you want to do it yourself or not. My 17 year old son changed the clutch on his Tracker by following the repair book, so it can be done. It's better if you know someone with experience to help you or at least be available to answer any questions. Good luck.
