Using the "Arthur Dalton code reader", I get only one blink on pins 8 and 14, but when I use the button and led on the 16 pin DTC, I get codes 17 and 26, so it is probably the O2 sensor that is causing the light - at least according to some of the lists. Does that sound reasonable for a 94 E320 wagon, which is definitely a 124 with chassis #: 1240921F270482?

I gather from the posts that this car has only one O2 sensor - right?

Thanks!
