Thanks Mike.

I read your long web page. Very nice!

Unfortunately, unless I missed it, it doesn't seem to address 0154.

The 0154 has been somewhat intermittent. I would reset the codes and it wouldn't come back for months. Sometimes the CEL would come on, but then turn itself off after a day or two.

I will say that last week, for the first time, instead of 0154, I got 1128 and 1130. I've since cleaned the MAF and throttle, and checked the oil vacuum. They haven't come back since. But interestingly, 0154 came up almost immediately and seems to be lasting. That's why I posted this question.

I'm still not sure I understand your response. If the problem is wiring in the sensor or the sensor connection, if I swapped the sensors L and R, wouldn't that be a good way of eliminating that as a problem? I've seen way too many guys with 0154 just jump and buy a new sensor, only to have the issue come back up. I'm trying to avoid that first mistake.
