i just installed the LT4 hot cam on my 96 lt1, i have the hypertech for supercharged, cam, and headers. well i do not have a SC.. but its optional to install the program, well my problem is that the car is idling on 500 rpm or lower, so i used the hypertech to bring up the revs to 1000, and nothing happend, what should i check besides vacums. im probably gussing its my IAC or MAP... any sugestions????

 

Iac

 

Is there any way to clean the Iac not removing it from the TB?????????, since its a trip going there!

 

Might want to test it before you remove it. Courtesy of Shoebox:

thanks ill check it before, well found the problem,,, the last owner of my car, had the egr unpluged since it was stuck and so, if there is an air leak the only posible way to lower rpm when there is a leak is closing the tb so i just opened it alittle bit with the torque screw and problem solved! 800,,, 850 rpm on drive! nice! thanks anyway!
