So my last few posts have been about my Acura MDX acting up. That was about 2 months ago in mid-November. Unfortunately, the check engine light issue has continued, although it's just the one code now. That code is P0420 and is apparently for the Catalytic Converter. It goes on and off at random times, and the 2 times I've mentioned it to Acura of Bellevue, they have just turned it off and said everything is fine. The light / code then stays off for another a week and returns after that. I can't tell if it's a specific type of gas that I'm using that causes it, but the Check Engine Light tens to come on during long (1 hour or longer) drives. I've been trying to find ethanol free gas, as I've read that Honda and Acura's sometimes have this issue due to ethanol, but I haven't been able to find any yet.
Stay tuned.
