CEL P2A00 advice
Damn CEL came on today. Had the code read and it was P2A00 (Bank 1 Primary O2 sensor). Haven't had a chance to crawl under the car yet to check for anything but plan on doing that tomorrow. Hopefully it's just a loose cable or worn wire. Car seemed to run fine even with the CEL on.
What I really need to know is, is it safe to push the car hard. I have a Solo event on Sun. but don't want to risk doing damage to the car. I thought I remember hearing in the past that when an O2 sensor acts up the ECU defaults back to open loop control meaning the ECU isn't compensating fuel trims based on O2 sensor feedback. If I was bone stock I wouldn't be too worried but since I'm running LTH and a CBE Im afraid I might end up running overly lean.
