I have an 03 XtraCab Tacoma, 2.7L manual. I suspect the front O2 sensor is gone. The Check Engine light is on, there was 2 incidents where the engine could barely keep idle, and my gas mileage has taken a beating. I am hoping to get a local mechanic to check the computer today. He said an OE sensor is $260. I found a DENSO OE sensor for $188 shipped. Is swapping an O2 sensor a big job?
