A little more info will get you responses. Also next put your car problem posts in the Infiniti Online mechanic section.

Hesitate when driving or in idle? or both?

Yep, do a search and read the posts. This post should be in the Infiniti Online Mechanic Forum where you will find most of the information concerning stumbling at idle and tip in.

How is your intake path, EGR and IAC valves, and also fuel filter change intervals, BG44K schedule, and any rail flushes you have done?

New parts are nice, but may address only part of the problem, or none of it at all if misdiagnosed.

Give Joe a call about a MAF connector, sounds like what my car doing right now and it needs that.
