Re: 96 XJ Hesitation when hot & cant rev

I followed the wiring loom for the front 02 sensor from the connector straight up to where I enters the bulk of the electrical wiring behind the power steering pump. I opened the loom, non of the wires appear pinched or burned. The rear 02 was the same look with no visible issues withnthe wiring. I have replaced both sensors with NTK branded 02's. I do have access to a good scanner with live data. The STFT B1S2 is at 99.2%. Ive never seen that before. The two 02 voltages range from 0.380 to 0.942.
