Hi

I have a 1987 300E live in California, however the car is from the east
coast, so it is a 49 state car.

I am up for my smog / emissions test in a couple of months.

The NO have been high the last two tests.  And am afraid that they might be
even higher and fail the upcoming tests.

Here are the results of the last two tests.  Any ideas of areas that I
should look into would be a great help.

Thanks
