Having a weird single cam issue that I can't seem to figure out...whenever my car warms up, I experience bad hesitation under 2k rpms. I have to give it a lot of gas to get it going. It also idles pretty rough.

I've replaced all the cheap stuff, cap and rotor, wires, coolant temp sensor, fuel filter, tested MAFs, tested TPS, cleaned IACV, and checked timing. When I put in fuel injector cleaner, the car runs slightly better for a week and then gets worse again, so I'm leaning towards a fuel issue.

Has anyone experienced anything like this before? Advice is greatly appreciated.
