Im kinda going towards the IAC as well. if it is the EGR, can he/she just removed it and put the blank plates? then test it out? the engine light will be on but it should work correct?

sounds like you're getting closer.....it'd be nice to have a scanner to see what's going on there with your iac counts and what not. You can almost rule out th coolant temp as the issue......normally the symptoms of a bad coolant temp sensor will be exactly opposite of what you're describing. It'll run fine cold but when it hits closed loop it'll flood itself out. The first thing I would do is probably pull that iac and throttle body and give them and the MAF a good cleaning. Also, make sure you don't have any vacuum leaks. The pcv hoses on these cars like to crack right where it bends to go into the intake on the passenger side.
