Hey guys I'm wondering if any has had this problem? In the past few months every time I go to start my car I have a service engine soon light and the engine seems to be running in limp mode. Now if I hook up my laptop and connect to my emulator and upload the current bin the ses light goes out and the car runs great. It does seem to hold the tune after I turn off the engine but only for a couple hours at most. I have not changed the tune in the past year so I am always uploading the same bin. Could the battery in the ostrich be dead?
