[MSCW list] Lean condition

[Lawrence Roberts]

Doug, here's a very detailed article on you're lean condition trouble code.
Not specific to the Miata but excellent otherwise.

Nothing noticeable has changed regarding driveability.


The OBD scanner tool is showing this for the freeze data:

>From what I can tell if I drive the car around with the OBD tool connected
and showing real-time graphs of the O2 sensors and the MAF sensor, they all
look like they are behaving normally.

I'm going to clean the Mass Airflow Sensor with MAF cleaner.  If that
doesn't work, I'll take the car to either PBC in Chantilly, or one of the
Rosenthal Mazda dealers (I live in Maryland).  

Just wondering if anyone else has had the problem I'm having.

Thanks,
Doug
