I have a 2003 EGC EFI with 21,500 miles, it has had a stage on with slip ons.&nbsp\\; Yesterday I was traveling at 60 mph for about 20+ miles, when I came to a stop sign the idle dropped to about 550 rpm.&nbsp\\; Then it stalled, it fired back up and I had no more problems with it.&nbsp\\; Does anybody know what the problem could be??

 

I called the dealer and thought it could be an air leak at the intake.&nbsp\\; Does that sound right?

 

intake air leak would be constant, not a one time thing, I believe. Consider checking your battery clamps.

 

TO CHECK AIR INTAKE LEAK USE CARB SPRAY WHEN U SPRAY IT THE IDLE SHOULD GO UP

 

mine does the samething once in a blue moon, im clueless iv checked everything

 

+1 on check the battery. happened to me and it looks like it was a loose positive cable.

 

If it was a car, I would say the idle Air Control Solenoid got stuck closed during your decell. It is a Delphi component like the ones on a GM car. But check the battery cables and intake seals. I lost a seal at 26k. Hard as rocks cold and the rear one had a crack. The computer controls do try there best to keep it running under most conditions.
