Help with some Codes
Just recently I started throwing
• DTC P0134 HO2S Circuit Insufficient Activity Bank 1 Sensor 1
• DTC P0135 HO2S Heater Performance Bank 1 Sensor 1
• DTC P0155 HO2S Heater Performance Bank 2 Sensor 1
Car fell on its face a couple times with a little hesistation. I got under there today and didnt see any melted wires or anything unplugged. So is it safe to say I killed the O2 Sensors and need new ones, and the fuel was the culprit?
Car is an 03 Z06 with CAI, LTs, Exhaust. Rear O2s are tuned out.
I was tuned on 93, would it do any harm running 91? I like to open her up when I get the chance so I dont want to be stuck driving like a grandma
