Still hesitating

I changed out my PCV valve...it was needed...bad. It didnt make much of a differance in the feel of the car and how it performs. The car still hesitates a little bit in the lower RPM ranges...any idea?

New MAF - done
New KS - done
New Spark plugs - done
New PCV valve - done
New Fuel Filter - done
New Vacuum hoses - done
No codes being thrown, with the exception of the EVAP line code. Ill change that hose eventually.

I have heard of this problem happening on a few maximas, and it does need to be solved. Any more ideas?

Checked coil packs, and they are all fine. Throttle body I havent cleaned yet, but I also havent had the time...I will try that as soon as I can. TPS is what?

TPS = throttle position sensor.

The coil packs typically fail under load - so this might be your problem.

Definitely give the TB and IACV (idle air control valve) a good cleaning first.
