Thanks, I will ask the shop to be sure they cleared the code, and they did replace both sensors for the second time.
Afer the bosch sensors were put in the codes still read p135 1/1 02 heater failure; p-141 1/2 02 sesor heater failure; and po-138 1/2 02 senor shorted to voltage.
I added fuel injector cleaner today, "lucas brand", heard it's better than gunout.
It was misfiring and idlin really rough. The idle is better now, and the as mileage has improved, but the light is still on for check engine.
