thanks everyone for the great ideas on this idle problem.

so I started with the simple crap... changed the throttle sensor, changed the air idle control, cleaned the mass airflow.... nothing seemed to work. then I noticed that when I turned off the car I heard a hiss.. changed the (EGR exhaust gas valve ) and it helped a lot but still kept dyeing while in park...... so I looked and saw a small rubber air hose next to the( ) was split so changed that and while I was changing that I felt my hand get sucked up.... WELL GUESS WHAT!!!!!!!!!!!!! turn out the people who installed my supercharger seemingly forgot to put a seal on this valve in the picture, the main connection to the ( EGR exhaust gas valve ).... sure enough big vacuum leak.... so created a seal for it, weird shape, 1.5" circle with 3 bolts in a triangle shape and the hole in the middle. so after breaking my hand top fit fingers in that tight space.... I finished.... closed my eyes.... turned the car on and BOOM GOES THE DYNOMITE!!!!!!!!!! idle was at 800, park was great no spikes... drove it for a few miles to warm it up.. checked the seal and it seems like its all gone ..... last time im taking it to a mechanic.....

so thanks for all the help and ideas. woow.
