Hesitation at 2000 rpm when I accelerate too fast

I have a 2008 Patriot with 62k miles on it. I've been noticing that around 2000 rpm that it will hesitate when accelerating. I recently put in new spark plugs and unplugged the battery for an hour which seemed to make a slight improvement. At any rate I the hesitation occurs when you are in neutral and you hit the gas too fast.

I've looked at a lot of threads that mention hesitation around 2k rpm but nothing where it does this in neutral and simply pressing the gas too fast. I guess I'm leaning towards a bad sensor.

My first thought was why are you trying to accelerate in neutral and then thought maybe you have the 5 speed and are trying to get it going. Is that the case?

I guess I should mention that I first noticed this hesitation while driving and later realized that it happens when giving it gas in neutral.

I could still be the PVC but I also have heard that the intake could get carboned up and needs cleaning. If the 'mechanic in a can' doesn't help it will need to be removed manually requiring disassembly of the intake and chipping away the carbon. Try another can of cleaner and the PVC first.
