Momentary hesitation???? Please help

[gwp]

2005 2.5 Altima 200Kmiles
The car runs great, however, recently on a couple occasions while maintaining steady highway speed, there has been a momentary hesitation. It's sort of like a "jump" when it seems to loose power for just a second. Anybody experienced this? Fuel or ignition? Ideas appreciated

When is the last time you did spark plugs? That is my first instinct. Any check engine lights?

Plus are new. "service engine" light has been on almost forever. Thx much

I would get the codes off the engine light as that would likely point you in the direction of the root cause of the issue.

My 2005 Altima has a hesitation when you are doing quick acceleration like on an on ramp. I've taken it in numerous times for that and everyone tells me that was a communication lag between the computers.
