Was driving my parent's 11/84 300D-T the other night and noticed a lot of exhaust smoke on hard accels. This car has had two trap oxidizers and the latest replacement catalyst (or whatever MBNA calls it) and I don't recall it smoking this much after those respective parts replacements.

This car doesn't get driven much on the highway, mostly in-town. Does this sound like something is amiss, or is this typical for a car driven mostly at slow speeds and stop and go traffic.

Any comments or sugguestions appreciated!
