First are there any engine warning lights on? If so go to a parts store (NAPA, Advanced, AutoZone, etc.) And have them pull the code. Post it here.

Common problems depending on driving habits are O2 sensors, Fuel/Oil Filters, Air Filter, EGR valve, Clogged Cats/exhaust, Dirty Injectors, Dirty Spark plugs, or then again it could just be your 93r tune. I personally have a street tune that a shop near me did.

Check ur tires for proper inflation and alignment. just for shits and giggles.

If you're only making short trips, your mileage is going to suffer. I really advise against that, as you run the risk of hydrolocking the engine. Dump too much incompressible liquid in the cylinders and your rods will develop neat little bends in them, like this:

duct tape will fix that right up
