One problem related to o2 sensor has been reported for the 2003 Chevrolet S10. The most recently reported issues are listed below.
I have a 2003 s-10 with 28,000 miles. I have had to replace both co2 sensors and now it won't start. It just started jerking and the fuel pump and filter work fine. Its getting gas and has a new battery. The check engine light is on. It wants to start but it doesn't. Also the radio comes on when I turn it off. What gives? this is my 3rd s-10. . . .
