Hello All, Glad I found this Forum.

2002 idle jumps between 500 to 1000 rpms once the truck as warmed up. It stays consistent when first started a cold.

This just started since I recently moved. Now I am in a lot of Stop and Go traffic.

I will check the coolant level.
I already replaced the Air Filter.

I read where maybe I should idle it down.

Or do I need to disconnect the battery for it to Re-Learn?

Thanks
