My stang is acting funny as hell. When the car has warmed up and I have it in gear at a stop light with the clutch in, the idle starts to jump from 600 rpm's to about 1300 rpms. I have changed the throttle position sensor and the idle air control. Along with cleaning and then changing the maf sensor. What else am I missing that could cause this problem?

Quite a bit, actually. Before you throw more parts at it, go over this: http://forums.stangnet.com/698148-help-me-create-surging-idle-checklist.html

Hopefully that works. That or I am just going to strip the car completely and start all over. Putting the car the way it should be. Rice eating, Chevy *****ting machine

what kept causing me to surge and ultimately stall out was bad plumbing on the intake. my C&L intake pipe didn't agree with my Morosso fender wall kit, and kept separating. maybe part of your intake piping is letting in some unaccounted for o2.

Already looked into that. But I don't have a cold air intake. My car is 100% stock. I have been trying to work out all the kinks it has before I start doing any mods.
