Engine Surging problem

[IdahoSHOmom]

Hey all, I have an 89 SHO and between me and my father we have yet to figure out why the engine keeps surging at an idle. We have replaced teh fuel pump, cleaned the sensors, and last night i reset the computer, its not surging quite so bad now but I find that it tends to do it when the clutch pedal is depressed, I'm out of answers so if any of you have Ideas PLEASE let me know...
thanks

You might try cleaning your IAB via the procedure at SHOtimes. Start there, that is the most simple and cheapest solution. How high does it jump? Does it ever die? Good Luck!
