Last week my '91 iX was running perfectly as always when I parked it in the driveway on Wednesday. The next day when I drove it away, it was suddenly overnight running like crap, idling rough, and with barely enough power to make it up a little hill. It was sort of OK on level ground, but any little incline just about killed it.
It's showing a fault code of 1222, i.e. mixture too lean or rich, which could be any one of about a dozen things. (I have a list of things to check.)
The challenging part is that it has been brutally cold for the past couple of weeks here in Vermont (i.e. down as low as -20°F/-30°C at night, slightly warmer during the day), and my garage is unheated, so I'm trying to streamline the troubleshooting as much as possible.
Tonight I pulled the spark plugs, and all 6 of them were wet. I assume that it's fuel, and the car is running rich. I also removed the intake to check for leaks (a smoke test is not in the cards, I'm afraid), and though the boot looked intact and pliable, it was pretty well coated with oil, and some frost in there as well. I think that should be pointing me to something, but I'm just what sure what. I'm also wondering if the cold has anything to do with this. Ideas?
