Hello everyone. I got a 97 vette on a trade. This is my first ls car. The car runs pretty good. It has a full exhaust on it. The previous owner did away with the cats and 02 sensors. I am getting a check engine light. I'm not driving the car just trying to figure out where to go from here.

I ordered hp tuners and the front 02 sensors
Iam under the assumption that you need at least the front 2 o2 sensors or the car stays in open loop witch makes it run rich. Idk how long he ran the car this way, but is there anything else I should check. Can running the car this way damage the motor?

Sorry for the long post and thanks for the help.
