Hi again all! I replaced my upper plenum,gasket,lower gaskets.had a code p0420. Catalyst inefficient bank 1. Cell went off. About a week later,80 miles or so,cell came back on. P0420. Got 2 new oxygen sensors,as Delco brand,try too install tomorrow. Did some googling,and came across, carb cleaner sprayed in cat, !
Liquid kilt sucked through brake booster line, cataclysm in a bottle, distilled water sprayed through intake,and lawyer thinner,a gallon too half a tank. Think any of these are worth a shot? Figured since I'm gonna have the sensors out,spray car cleaner in, some distilled water,followed by the laque r thinner thing. Scotty kilmers thing.
