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
