Gave it some attention this weekend. New AC delco front O2 over the parts store garbage, readings are much quicker and seem more accurate now and a couple O2 codes that I've been ignoring are gone. MPG bumped a good amount. Bent the tabs back on the obdII port so I don't have to wiggle the connector to get it to read. Bandaid fixed the ZZP **** valvecover gaskets again until I get new valve covers... Think thats it.
