Seems much better- last time through emission testing it was only NOX that was very close. I'm hoping it was out of range last year... New plugs and an oil change before we pay the test station.

I am pretty sure it is rich.
I had a center muffler failier around Halloween, when I replaced It (both it and rear muffler had been off for 1½ months) I expected to see a big improvement in mpg that never appeared. It has been a little slugish as well.

Was that temp sensor on your 86'? If so where is it exactly (side of the block?) and any tips on the test?
