Ive got this really weird hesitation/miss, if i am slowly accelorating or just cruising at a steady speed. Doesnt happen all the time, and as soon as i put my foot into it it will clean itself out and pull like normal. Any ideas? What can i check. It doesnt happen if i accelerate hard. Happens around 2000-2500 rpms usually. Also when the car is idling it will kind of cycle from idling smooth to idling just a little bit rough.

I have my EGR disabled, but all of the hookups are still there and connected. Could this have anything to do with it. I kept getting an EGR code b/c there is not enough back pressure in the exhaust so i just disabled it. I was having this problem before it was disabled though.

Plugs are fairly new, wires and fuel filter could probably use a replacing. I think i noticed this started hapening around the time that i put my headers on. Anyone with any ideas?
