Question about 2000 Chevrolet S-10
This problem has been going on for about a month, getting progressively worse. The truck sputters when idling and hesitates under low rpm/ acceleration conditions. I had a code for an oxygen sensor come up, I replaced the sensor which took care of the code but no improvement to how the engine is running. The only other code is for a P179-Fuel Compensation Sensor. From what I hear this code is related to the fuel composition sensor that sense the fuel mixture of E85 and gasoline. I do not believe this is the problem, as that code has been up for over a year and I only use gasoline. I also read that a burnt valve is a possiblilty, but I have not run a compression test. Any ideas would be appreciated.

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!!
