Answer
Hi Buck, the first thing you need to is relearn the idle. To do this run the engine in gear at idle for 10 minutes, now turn it off and restart after 30 seconds. Now again run the engine in gear at idle for 5 minutes, this should relearn the idle in the computer. This needs to be done any time the battery is disconnected or dead.
