whats up so I recently put on a spark plug non fouler on my 02 sensor due to the fact I was getting the 0420 code. Everything worked fine for like two days. Seems to me that long trips ie maybe 30 minutes will trip the cel with the non fouler installed I live in Miami florida therefore im thinking the heat outside and from the engine might be tripping it? Any other suggestions on ideas that maybe I can incorporate to the non fouler thanks
