Fuel economy experiment without ILP
I just did an experiment to see whether fuel economy is affected by not performing an Idle Learn Procedure. I've had my battery disconnected a lot in recent months and my gas mileage has been a couple mpg lower than normal, so I wanted to test this theory in a controlled experiment.
I had my battery disconnected for half a day at the shop during a remote starter installation. After hooking the battery back up, I immediately left for my parents house, let the car sit for 2 days then drove back today. I always get between 19-20 mpg during the 500-mile roundtrip, but this time I only got 16 mpg.
I'm convinced that disconnecting your battery for a few hours will trigger the need to perform an ILP or else your gas mileage will suffer by a few mpg.
