Thanks. I'll go ahead and replace cap/rotor/plugs/wires and see where I'm at. I've noticed a few times when driving in town the slightest hesitation on acceleration at times...almost imperceptible, but I've drivin the car for 8 years and have developed a sixth sense about when something feels different. that could be in line with all this, too, yes?

I took a road trip in July and got about 37mpg. Unfortunately, my trip reset button long ago stopped working, and I haven't been disciplined to write down mileage between fill ups, but i'll start tracking to see how i'm doing.

From what i've been able to browse on the forum, you're pretty much a Brickboard institution, and now i see why. Thanks for your responsiveness and clarity. I really appreciate it.
