alright, I already asked everyone about this, but I need some more ideas. I recently had the car diagnosed after installing a 350 and an appropriate chip. I've got a vacuum leak that is causing rough idle and sometimes the car stalls out. My #5 plug was shot, and the guy at the shop contributed this to the vacuum leak. Where would this leak be at? In the throttle body, intake manifold, or in the EGR unit. I figured that it would be in the EGR or in the solenoid for the EGR, but I can't really test it here at school. Anyone with ideas drop me a line. All of the cylinders have been running lean apparently.

hook up a vac gauge! what an idea! i think it needs to be at 15 not to sure though

I would do that, but I can't in the school parking lot. Besides, my vacuum gauge is in MA. and I'm in NC. I'm pretty sure that it isn't in the manifold now, I took some carb cleaner and sprayed it along the manifold to see if it would cause the engine to bog down, but it didn't. How can I test to see if its the EGR or the EGR solenoid. I tried disconnecting the hose from the EGR and I didn't notice any change in the engine or anything.
