2000 TJ stalling

My 2000 TJ with 150k miles recently started stalling after I come to a
stop, as if the idle speed is way too low. It seems to run okay
otherwise. It's intermittent, the check engine light is not on and
it's not throwing any codes. One time I disconnected the battery for
a while when it was stalling in the driveway and when I reconnected
the battery the idle speed went back to normal. I sprayed contact
cleaner on the connectors for the TPS and some of the other devices by
the throttle body and I've replaced the battery, and it's still
stalling. Next step is to clean the throttle body - any suggestions
on what to check out after that?

Thanks,

John

Do you change spark plugs by thirty thousand miles:

Try cleaning the throttle body. They get carboned up after a while and need
to be cleaned.

I pulled the throttle body and gave it a good cleaning - idle air
passages and the tip of the stepper motor were carboned up pretty
good. Started right up and settled to a normal idle and stayed
there. Time will tell but I think this problem is fixed...

Thanks!
