These codes are codes regarding failure. The code P0300 means repeated Engine Misfiring. The code P0303 means Repeated Misfiring of Cylinder Number 3. Kindly contact a technician to get both checked. Their Heads must have been misplaced or broken due to misfiring.
Thank you sir, Have a nice day.

Chrysler intrepid 2003 obd 2 code P0441


Most common problem causing this code is the purge solenoid. A quick smoke test will show if you have any leaks in the system. If no leaks and the fuel cap is installed properly it's the purge solenoid.

Diagnostics trouble codes


Could be a loose gas cap, or it was left loose once. P0441 means: p0441- evap purge system performance. In some cases disconnecting the battery over night will clear the code.
Take off the Negative cable only always wear safety glasses when working with a car battery.

Check your gas cap first make sure it is tight
