Anyway, it happened again after work, so before the fast idle even died down I shut the car off and disconnected the battery. After the ECU reset everything is fine and car drives normally again. I think my tune is somehow walking itself into a bad spot after several weeks of running, that is why it is fine once it warms up. Whatever table is getting bad must reference coolant or oil temp.

is you tune maf based or speed density
