Well you guys were on the right track. luckily i asked or i would have removed the whole supercharger and IAC for no reason. i looked over the vacuum lines with the car off and i made sure there were no breaks or loose connections. and then i started it a few times for a bit and felt for leaks. i was about to give up when the lines finally warmed up a bit and would collapse and suck themselves closed at idle. went to auto zone and got some stronger lines for the vacuum lines and it seems to be idling at 800-1000 again like it should!
i replaced most the vacuum lines with the install of the supercharger but the instructions said to use several of the original lines so i did. should have known better. it was the bigger line going from what use to be the side of the air box down to the bottom driver side of the engine. the supercharger added some distance causing a kink in the line.
Thanks guys, if you wouldn't have told me vacuum problems i would have wasted a whole day off at my dads place on my back.

|Mother Focus||Leak can be almost anywhere, there is the smoke test but what I do is fix a piece of a tire tube over the air intake (turbo in my case) leaving the fill valve exposed so I can blow some air in with a compressor(3-4psi)use a spray with soap and water like trying to find a hole in a tire. Spray over throttle, IAC, vaccuums, intake manifold, break vac hose, etc. the iac might bubble some but it's normal, not on the flange though.|

|Michael_Price1990||Well it was running fine untill recently. i was going to get a tune with tom after i get my tax return hopefully soon. i installed the supercharger a few months ago and it has been driving and idling fine untill recently. and as i stated when i unplug the IAC it idles fine. where should i check for a vacuum leak? any diagrams online i can look at? i think ive checked all the vacuum lines. at least all the ones i messed with when adding the supercharger|

|Mother Focus||Seems like a vacuum leak, do some leak tests until you find it. Who's tuning it? Did it idle before?|
