2007 Jeep Compass - Slow Acceleration

Recently my wife's car, 2007 Jeep Compass, has been running a little "off."

Long story short, her Compass has a slow/sluggish acceleration, and the engine doesn't sound like it used to. It sounds loud when running and when at idle...best way to describe it, it sort of sounds like she's running an 18-wheeler under her hood. Any ideas what it could be?

Any help would greatly be loved

Need more info. How many miles. Which transmission. Have you changed spark plugs? Transmission fluid?

Sorry about that. It has a little over 125k miles on it and it's A/T. Have not changed the spark plugs. For me it seems to be coming from the belts. I don't think it's the tranny though. I will check alll those out though.

Could be something simple or something not so simple.

Does it should like a desiel? You could need the valves adjusted, or you may have something broken in the valve train. If it just feels off, with an "odd" idle, change the plugs filters, fluids, check the plug wires, and then just go to the stealership and have your ecu reprogrammed for the engine and CVT. My patriot felt off after about 50k, the dealer did what I said and it was fine after that.

No plug wires to check! With 125 K on it and not having changed the plugs it sounds like a good old fashion tune up could go a long way and inspect the belt and pulleys while your at it.

This. Plugs are supposed to be changed every 32k or 2 years. Start there.
