When I turn off the engine and restart the engine trouble light comes on. The mechanic resets the new O2 sensors and the engine light stays off.
Then if I restart the car the trouble light comes on again.
The mechanic said it is the computer board in the car that needs to be changed.
I can't get an emissions test unless I have the O2 sensors reset and don't shut off the engine.
Any thoughts on this diagnosis and what the cost to replace the computer board is?
Thanks,
