Stop in for a cup of coffee

I remember the photos of LA smog as a kid.
Fortunately wasn't that bad the times I visited - 20 years later.

Most of the emissions stuff works well enough and doesn't hurt performance or economy much, now.
There's a few emissions items that were definately a big drag both in performance and economy. Really hated what the timing delay did to the six cylinders. IMO that was the worst. Not much love for early cats either. Fortunately even the big companies got wise and started using high flow/low cats - my recollection was the Fox chassis mustang and t-birds lead on that front amongst the big three.
