2002 KJ idle question

2002 KJ a few days ago idle would stumble when KJ was cold. I would pull up to stop sign and apply brake idle would drop to 300 or 400 rpm. I could not figure out the connection between applying brake and idle stumble. After KJ was warm problem would go away. Any thoughts are appreciated.

Ever had the tranny flushed? Sounds like the torque converter having issues, to me.

never had a flush but dropped pan and changed filter. I know that this method leaves old fluid in converter but never had any tranny issues before thanks for the imput.

Check out this post from when I had a similiar issue. I cleaned out the throttle body and it has been fine ever since

I had the same thing happen to me last Saturday. When I came to a stop the engine died. Started happening when it was 23 out. Cleaned the throttle body out like the post said, added some fuel injector cleaner and the KJ's running like a scalded something or another

As usual, this site saves me bucks :BANANA:

Cleaned Throttle Body and IAC and Forced Flashed the PCM. Runs and Idles great. Sometimes its the simple things that will correct issues.
