Symptoms of bad front O2 Sensor??
Hello All,
I've been having some stall problems recently. Right before the actual stall, my air/fuel ratio sensor begins to dither at a very slow rate and the engine dies. This happens occasionally as the truck slows down or stops. Fuel system & plugs have been checked so I'm running out of ideas. Truck hasn't thrown and CEL lights for me to confirm. Any diagnostic tips to suggest??
Thanks,
Michael
