Need help with check engine light
Ok so I went to and from the store to experiment...apparently if I drive my grandpa car like a grandpa, the cel wont come on, buuuut at about half throttle the trac off light will pop on first, then the cel will come on. distance, or time doesnt seem to make any difference since *** soon as I giveitenough gas to get ahead of traffic for a turn, or lane change its cel time. The weird thing is the code clears itself anytime the motor stops running and won't pop up unless I'm driving.
my searching had led me to o 2 sensor failure (the gas smell and tiny missfire confirmed this ) new o 2 sensors and I still have the cel although the gas smell and backfire is gone. I tried pulling the code at the shop with the scanner but it keeps saying code bank empty. there are also no symptoms and the car is running like a champ. what other component failures would lead to the cell and trac off light illuminating during certain driving conditions? also I looked up the self scan trick, but reading it made no sense. I'm more of a visual person so if someone could tell me what I'm supposed to be seeing and where it is throughout the steps of the self scan would be great

Ok after a bit more investigating it appears I need to connect the two portions of the giant connector under the hood that plugs to nothing...can anyone confirm?
