Since I got it last year with 65k, now 73k, at speed, holding speed, at what ever speed I can feel a little pulse or surge in the car. Sorta like air intake thing or throttle type of slight light surge in the car as I drive it. What could this be?

 

It is not real bad at all, just curious now that I think of it.

 

lots of little things could cause surging, mass air flow sensor, fuel filter,clogged injectors, bad plugs/coils... all relatively minor, and can be checked pretty easily. I'm sure there are others.
