I just changed the lid on my car about a month ago and as soon as I took it out and cranked on it and I mean I launched it like it was stolen the check engine light came on. I reseted the check engine light and it ran fine for 200 miles then today I decided to tatoo the pavement :-) and it came back on and it reads LOW VOLTAGE BANK 1 BACK O2 SENSOR.

Any recommendation on witch sponsor to order from and low voltage is kind of weird isn't it.
