Jeep Liberty 3.7L P0300 Multiple Cylinder Misfire

My sister has a 2006 Jeep Liberty with a 3.7 Liter engine and had an issue. She had it put on a computer for testing and got an error code P0300. She paid $350 for a garage to put on 2 new coils that didn't fix the problem. I diagnosed it down to a $36 oxygen sensor and that fixed the problem.
