Hey I've had my mustang for a few years now (1998 manual 5spd). Recently the starter died on me so I had to bump start it a few times to drive it to the shop. I believe that's when the issue arose. Now when I start my car, the voltage reads super low and the oil pressure super high. I just put in a new battery and got an oil change too. And this occurs 9 times out of 10. On that tenth time, everything is normal and completely average. So I'm not sure if it's just a weird sensor issue or something. Any experience with how to fix this?
