After reading about it on these forums, I installed a cheapie vacuum gauge on my car, a 1989 Eagle Summit DL, with 1.5L engine and auto-3 transmission. The gas mileage increased from 25.9 mpg to 31 mpg (city driving) on the first tank.
Vacuum gauge: $16, sale price and with coupon from Harbor Freight.
Thanks to all for the great ideas! I especially like this site because most of the ideas are confirmed through experimental data. I look forward to reading, modding, and (hopefully) contributing in the future.
