Thanks, Mike. I sent an email to Marc Haibeck last night and he replied with similar thoughts, like maybe it had gone into limp home mode. Marc suggested I check the chip to make sure it is seated correctly. I'll do that when I get to the garage tonight. I've also disconnected the battery and will reconnect it tonight.
