It fouled quickly and I had the same kind of symptoms as you. I replaced it with a Bosch 12013, single wire, which has functioned okay so far. Using mogas only so far.

Greetings, I haven't had a chance to do anything else with my O2 testing, but I've had an odd thought. The full story, is that I originally had erratic O2 readings with the rev-2 configuration. Primarily, this was staying on the mid, to low end of the scale, but would then just go away completely, as if it was way too lean. I had used the same sensor I used before, but now had the EM-2, rather than my old mixture gauge. It didn't take long before I noticed that the O2 sensor was falling apart, so it was replaced with the Bosch 11027 sensor that several of you are using. On the next run, the EM-2 read almost full scale, and I couldn't do much to change it with the mixture knob. I could hear the engine getting richer and leaner, but the reading stayed near full scale. The only time it would change was when I leaned so much that the engine was starting to cut out, then it would plunge to nearly zero. ------=_NextPart_000_0000_01C41830.76368D80 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Message
