The engine has an infrequent miss. It happens once it is warmed up, running between 1400 up to 1600 rpm, under light load. Doesn't matter what gear I'm in or the speed of the car. I've replaced distributor cap and rotor. Previous owner replaced plug wires at about 80,000 miles/ 10 years ago. Problem seems to be getting worse over the last 100 miles or so of driving.
