Kind of a dumb question...but do you make sure you tighten the gas cap until it clicks every time? I'm not saying that's the problem, but I Am saying that I've seen a lot of mystery CELs that ended up being only that.
good luck! :) |
"no activity" in regards to a o2 sensor, probably means you need a new one. that might be a good place to start....
