Unhappy And the saga continues.......

My 87 560 SL failed NJ emissions inspection (CO & HC). In a flurry of potential overkill, I replaced all of the injectors and the oxygen sensor, which was badly fouled with carbon. Unfortunately, I have no idea what the previous owner may have done to the mixture adjustment, but can refer to two symptoms:

1. When the car accelerates hard it sends out quite a bit of smoke.

2. Gas mileage, from what I can see, is about 12 mpg.

To me, this sounds like it may be running rich, but I have no way of telling, and am reluctant to run it through inspection again without making some effort to ensure that the mixture is correct. Are there any suggestions besides visiting my neighborhood M-B dealer and taking out a mortgage on my house at the same time?

1986 560SEC: 150,000 miles, runs great, but I've got to sell it (too many cars for one man)
1987 560SL: 122,000 miles, used to run poorly, now (thanks to forum), runs great!
1997 GMC Jimmy: Turned out to be a turkey.
1989 T-Bird Super Coupe: 150,000 miles, still runs great. Ford got it right.
