Those numbers were decipherable...........until the O2 came in at 20.8%!!!!!!!!

Does your engine not run on oxygen? I would've thought the tester would pick this up. Some oxygen in the exhuast indicates a fault but i can't be that high with the engine running, no matter how badly in runs. This means either the reading is false or you have a leak in your exhaust which can allow alot of O2 into the system.

The CO readings so that it could be richened up a bit.
