Code 64 and 65 together? I recently got my car back from a shop, and the car ran AMAZING. They found a burnt wire, an injector was defected (only 4 months old), and a few other things. The car ran so good when I got it back. But, all of a sudden it's running weird. It runs good, but not as good, ya know? So the car threw codes 64 AND 65 today. Those are both for the RIGHT o2 sensor, one for a lean and one for a rich reading. How are they both being thrown? What sense does that make? O2 faulty? Another injector? Argg!! help!

The best way to know is use Datamaster. Often one side causes the other to go wacky...
ie the right side has a bad plug the ECM reads a miss as lean (HIGH Oxygen content) the ECM therefore says hey I need to add fuel (adds to both) the miss continues so adds more now what do you suppose happens when it 'balances' for the miss?
Datamaster allows I think 20 free runs so all you are out is cost of cable. Once you use Datamaster you will buy it.
Good luck
