first off...post your year and trim in your signature. also the tech info section has codes already listed. this has been a big help to the members here. go to electrical, and then computer. There are codes categorized by vehicle year.

P0171 Systym Too Lean (Bank 1) - This is an O2 sensor in bank 1 it needs to be changed, it'* running to lean.

P0300 Random/Multiple Cylinder Misfire Deteced - Your engine is mis-firing, get a tune-up. It means more than one spark-plug is mis-firing.

P0441 EVAP Control System Incorrect Purge Flow - This could possibly be your gas-cap

and the other'* I have no clue

Also on the lean code, pull your battery cables off and inspect them for corrosion and clean accordingly.

There could be something that caused your plugs to mis-fire. Take the car to a shop, and have them tell you exactly what needs replacement. I'm not telling you to have them fix it, but atleast they can tell you exactly what is bad, and needs to be replaced. I'm willing to bet the O2 sensor is causing the mis-fire. Or at least part of the cause. Running to lean can ruin spark-plugs quickly, as can running to rich.

Wow...for a girl, I sound kinda smart
