Hunting idle when warm

Hi guys,

My car, when cold, starts and runs great. When I do a hot restart I get a low idle and it hunts up and down. I took a log and have attached it. Any suggestions?

They won't/can't do anything for you unless you also post your tune.

search for IAT heatsoak and you'll find plenty of threads on this, best solution I've seen is the "anti-ideal gas law" MAT curve someone posted, I think it was Braineack.
