No I have not cleaned the IAC.

I did test the idle and throttle up response.

IDLE = smooth

THROTTLE UP = smooth ( might have noticed some mild, very mild issue at around 2700 RPM but not sure - ran it up to 3000 + with no roughness noticed )

Driving it in to work in the morning, may let Jeep service take a look at it.

 

the iac motor has a lot to do with idle ciontrol

 

I am aware of that but keep in mind, we have now four stalls.

Two of them occurred sitting at a light and two of them occurred driving at speed.

The IAC will be looked at, and I am not ruling it out at this point.

The last time I have an IAC go bad on a vehicle it really screwed up the idle something awful. On that vehicle it was a 50-50 shot, either the IAC or the TPS because as soon as you came off idle it smoothed out nicely. It almost looked like there was a bad spot on the TPS but I asked the parts department .... " Do you sell more IAC's or TPS's? " and they responded with IAC, we bought one .... slapped it in and all was well.

Of course that was NOT on a JEEP, so I know things can be different.
