While sitting at a stoplight yesterday my 07 JK acted like it wanted to stall. The rpms dropped and engine stuttered but immediatly recovered. This happened three times. Any ideas?

 

I am interested too. It happened to mine also?

 

Mine too. '09 Automatic. It only happens at the first red light or stop sign. A few seconds after coming to a stop it stutters. After that it is fine. It has never died on me.

 

Maybe an issue with the electronic throttle response...

 

Mine does it too, but I think it has to do with a combination of the weather and the change in gas mixture. During summer months gas is switched to run oxygenated and I think that throws the ECM off a touch and takes it a bit to get re-calibrated, but that's just my two pennies...

 

Something silmilar was happening to my '09... It turned out to be a faulty spark plug.

 

Maybe i will try the plug thing. Any suggestions on new plugs? The throttle body has been cleaned but still happens. I have an AFE CAI and AFE throttle spacer but it did this before the change from stock. Seems to do it more when its warmer outside. Im in NC. One day its 48 degrees the next it is 74. Today its 74 and has been real bad but will not stall.

 

Mine has done it too...stalled a few times just minutes after starting. few minutes later everything was working fine.
The trans-oil-level was too low. Refilled it and it was gone

 

I have a manual and the fluid is full.

 

Had the same thing happen and it threw a few codes (high idle being one of them). Turned out to be the PCV valve that affected eletronic throttle control. Part is on order.
