s14 ka24de weird idle and hesitation

[misterdumby]

I have a 95 s14 with a stock ka and it just started acting weird...
The car will idle fine but stumble every now and then like its missing, and under acceleration it will bog down almost to the point to where it dies. Like for example I was driving home from work the other day and slowed down into 2nd gear, gave it some gas and the car bogged down a couple times before it picked up and decided to go. Same thing happened when I was stopped at a traffic light, had to feather the gas so it would get past the hesitation so I could accelerate. I've replace the maf, fuel filter and fuel pump and it hasn't changed. Also I checked the spark plugs, and injectors which all seem to be working fine. It seems to do it more once the car reaches operating temp.

Has anyone else had this problem?
My next guess is iacv, coolant temp sensor, tps, or 02... but I'd like to narrow it down if possible
