I just bought my maverick and when I got it home I noticed the check engine light would come on for a second and then go off. Then check engine would come across the display. And some times all the dispute lights light up and then it says performance key like when you first turn it on. And does this repeatedly every 30 second to two min. I figured it was a lose connector to the gauge so I unplugged the connector and plugged it back in a few time and I did not help. I did check the battery cables and they are tight. So is the gauge bad or is there anywhere else to check for a lose connection. Or anything else I should be checking?
