Is your Check Engine light on? If so, I suggest running the self-diagnostic procedure with your ECU. It might indicate a bad fuel injector, which have a tendency to work sporadically when they are failing. This causes a very noticeable hesitation, especially at cruising speeds. Unfortunately, this would be a costly repair. I hope this isn't your problem, though it's happened to my 1990 N/A on two separate occasions. Runs like a charm again when fixed though.
