Engine Mechanical problem
1992 Chevy S-10 6 cyl Four Wheel Drive Automatic 214000 miles
I have done a complete tune up and then some. Plugs, plug wires, cap, rotor, air filter, coil, water temp sensor, map sensor, throttle position sensor, new injector. The problem is when it is at idle and while driving(usually when I am just cruising, not under exceleration) it hesitates or almost cuts out, or lack of power then service engine soon light comes on but is only on a minute or so. When I put it on the computer it says O2S rich. I just dont know what else to do.
have the same problem?
