[QUOTE="Adfalenski, post: 1492263, member: 21752"] If the battery was disconnected or ECM were unplugged for a long period of time, the ECM memory battery could have died and lost your sensor mapping. That takes the ECM back to the factory base tune. The factory base tune may not allow for the heavy load and therefore idle is dragged down. The factory ECM takes up to 200 miles and/or approximately 10 cold to hot engine cycles to repopulate/reprogram the sensor map. [/QUOTE]
