Problem with TPS?

[S13Nissan240SX]

Hey guys,
I've been putting up with a problem that I think I might finally try to fix. I had my engine rebuilt last summer and the car has been running great. Occasionally, however, I'll hit the gas and the car hesitates or rolls slow for about a second, and then it starts picking up speed. I think it might be the throttle position sensor but I'm not sure. I replaced the unit but I still have the problem. I think I get this more when it's hot and/or when the AC is on high. Has anyone else had this problem? I appreciate your advice.

Yeah... I heard you had a problem with your TPS reports... Did you get the memo?

Anyway, sounds more to me like your MAFs.

Yeah, definitely check your timing!

fuel filter maybe? if it bogs when you open up, maybe it's that.

I tried adjusting my TPS and now have lost all pep.
Does anyone know how adjust it like acording to the FSM?
