Took car to Autozone pulled code of P0420, they could not reset light. Looked on forums about code, could be cats or could be o2 sensors. Saw that converters should still be covered under the 8 yr 80k mile warranty, but also was a possible reflash on computer.
Thought it could not be that bad. Took to Maxwell Ford in Austin.
$135 to reflash the computer, $13.50 for hazardous waste fee/Disposal plus tax. I asked about what was disposed, but they would not say and would not take the charge off.
Just an additional 10% profit. Too bad I did not have the time to do it myself, I feel sorry for those who cannot do any car repairs at all and get ripped off all the time by the stealerships.
