i have a 1997 volvo 960 with 86000 miles on it . a code came on and said num 1 cyl not fireing so i changed num 1 and num 6 coils to see if it was the spark plug or coil. after that the o2 sensor code came on instead.i changed them back the way they were and cleared the code and still the sensor code comes back on and not the other but it runs like it is misfireing

How did you try to clear the code for the O2 sensor? Do you have an OBD reader of some sort?

The only correlation that I've been able to see, cruising through a couple of websites, between the misfire code and O2 sensor code being thrown is a vacuum leak.

Which codes came up? Have you tried switching the #1 and #6 coils back?

I think you may have forgotten to answer the question.
