Piston might be partly engaged all the time (more so than normal, that is). Does the car pull to one side or the other much of the time?

Thanks. The car isn't throwing any CEL's but that doesn't necessarily mean everything is working in tip top shape.
The previous owner gave me the records of the things that were replaced and in January of last year they replaced the distributor cap/rotor and wire set along with new plugs. I just replace the plugs again on the 17th of this month.
I am planning on checking the fuel delivery system, maybe the fuel pressure regulator is stuck open or something like that. There was a new fuel filter replaced back in January of last year as well.
Anyways, I will keep this updated as I tune things up and record my mpg's.
