Is it too rich or too lean or something else?

I assume you are asking about reset / remap of ECU? I disconnected the battery and left it overnight. While disconnected, I pulled, cleaned, and reinstalled the MAF sensor. I reconnected the battery, turned the key to accessory position for a minute, removed the key, waited 5 minutes, started the car, and then drove it for 10-15 miles. The car ran like garbage at 5500 rpm+ before and now it is back to normal.
