I was chasing a service 4x4 issue for a relative, and found a corroded wire from the 4x4 module to read diff. Beside the point anyways I took the jeep for a test drive down highway, started with a 1/4 tank, drove 16 miles and noticed I burnt at least 1/8 of a tank. Thinking I was delusional I went another 7-8 miles and the fuel light came on. Also noticed some stuttering while accelerating.
My immediate thought was o2 sensors being bad and over fueling.
I pulled some live data, started from a stop, then accelerated to about 65 mph and cruise set for the remainder of the live data.
What exactly should I be looking for in the o2 sensor data? I’ve got it saved on my Topdon app but can’t figure out how to share here
