Hello, I agree with you resetting the parameters is not going to solve your issue. What I suggest you do is have the shop run a Air Pump System test to make sure the hoses to the Air Pump and the valve are good, then monitor the O2 Sensors to make sure they are sweeping. I have a feeling that the Air Pump works but the valve or a hose is not operating and this is your issue. You could also do a visual check of the air pump hose and see if you are able to actually see the hole or a cut in the hose. Make sure to look completely around the hose not to miss the underside where it is more difficult to see a mirror should do the trick.
