Error codes after replacing O2 and MAF sensors

It is more than one wire as each sensor sees its own short individually (each sensor is an individual circuit), all four sensors are shorted, hence the four codes, one for each short.

The generics were the culprit. Replaced all 4 with Bosch replacement from rockauto for 90 bucks a piece.

I'll try contacting the eBay seller regarding is advert that his sensors work on my 98 base. Wasted $160 though I'm happy that the CEL light has gone... Having the state inspection done as I type.

Thanks for all the help...this board certainly outperforms the car
