1993 940 NA Rex Regina

Bottom line - It turned out to be the cat after all.

Here's the saga. Overdue for emissions.
Round 1 3200 ppm Nox
Round 2 1600 ppm after changing plugs, air filter and running injector cleaner through and 1000 miles later.
Round 3 1600 ppm after replacing temp sensor and MAP sensor (had a code 1X)
Round 4 2100 ppm after replacing O2 sensor. My mileage is better! It was 12 years old anyway - probably due.
Round 5 217 ppm with new cat. Old cat was 1 year old Bosal. Nick at FCP found one made in NJ by A&B parts. What's interesting here is that these guys asked if it was Regina or Bosch, since they said they had a different cat for each. (However, the sticker said it was made in Canada)

So, hats off to Nick and FCPGroton for coming through again.
