This is a downstream/secondary o2, I need the pre cat.

This is my second insight. I started a thread about how I couldnt even come remotely close to mileage from my first insight, driving style hasn't changed. I'm getting the rich fuel mixture CEL for primary o2 sensor, and I can smell the rich mixture even at idle. After 40% throttle or so, I can smell raw fuel in the cabin. No fuel leaks, at least from the injector seals, rail, regulator...

There may be more than one problem, but the primary o2 is definitely one of them. I haven't thrown any parts at the car, done free maintenance, and purchased new fluids, and returned the other o2. I agree with you 100%.
