Question about 2001 Chevrolet Impala
Engine losses power resulting in engine shut off, but will start again right away. Occurs at any speed with or without cruise control. Otherwise engine runs great with plenty of power (205k miles) I have replaced TPS, Mass air flow, Crankshaft and Camshaft sensor along with the Ignition switch. No Codes have ever appeared. I do not know if it could be a faulty electrical connection or what.
I would check ALL grounds first and then main relays. Does this do it at a certain speed everytime or when ever it feels like it ???

How old is the Catalytic Converter, sometimes they will get clogged up and affect performance.

Hi. I would try changing the fuel filter. If its partially plugged up you could be starving for gas and that can make your emmission sensors give bad readings. Cant gurentee it, but it would be a place to start.

Hi! You must be frustrated by now! your code is marking that the O2 sensor is bad in bank 1. Did you replace the O2 sensor that is located before the catalytic converter? The S10 has an O2 sensor specially made for that cat. its about 30$ That would explain for your blackened spark plugs; your pc on the car is asking for more fuel. GOOD LUCK!!
