miata040127.txt Time-stamp: <> Need heavier beads of RTV on top to work as rain gutters, do on "top" rather than "side" like current RTV beads. I keep getting the "check engine" light. Need to learn how to get the codes. Barry says there is no useful scanner available for the car. It also seems to be running rich, mileage is also down a bit. I wonder if the oxygen sensor is fubar, and it is running open loop. Should we also take the O2 sensor meter from the MG and put it in the Miata, I want to get a wide-band sensor for the MG anyways.
