Hesitation? Holds RPM? Stumbleing at idle?

I also noticed that the EGR isn't moving with throttle anymore, like it used to. That could be it, but then again, the car has already had injector issues. Gonna do some testing tomorrow.

Heh, sorry I didn't post back. I figured out what it was. Very weird actually.

I painted my VC and then replaced the gasket (obviously) and put the VC back on. I then tried that shitty engine cleaner (didn't really work, needs elbow grease) and then hosed everything down. I covered a lot of stuff up, but didn't (idiot) cover up anything by the spark plug wires. Water got into the top of the spark plug and caused no spark. I just took out the plugs and cleaned them and it went back to normal.
