Welcome to the forum.

If you bought it with 1600 and now have 41K and never did anything but oil changes, the first thing you want to do is change the spark plugs and plug wires. That could solve your problems right away. There's a guide on top of the Tech & Performance section and although it's basically for the early models, the major steps are there for your model. You have no EGR pipe so there's a couple steps you don't have to do. For the non-turbo a good plug is the Champion Double Platinum #7570 and any good set of plug wires will do (Don't buy the wires from the Chrysler dealer unless they carry the MOPAR Performance set). Also make sure you change the air filter. That in itself will cause the engine to bog if it's stopping enough air from getting to the engine.
