Hunter P411

13 years old

Will replace next month with Hunter Hawkeye Elite

Hope to use it until I retire.

Will sell my old one if anyone is interested. Still works great.

You put a thermostat in trying to fix a P0420? I would be pissed also.

Check for any possible computer updates and replace the converter. Ask the customer if the car is burning oil, make sure fuel trims are normal and vehicle runs good with no misfires. Any of the above items will spell an early demise for a good converter.

It doesn’t do any good to sell testing time if you cannot diagnose the car properly. Make sure that every detail is explained to the customer.

For your first one, I would call a lawyer and ask. They will give you a flat fee for completion.
