I have an 95 s10. It has the 2.2 mfi system. Having idle problems as well as missing in low RPM situations. Will miss a little in overdrive, will down shift and will stop. If floored though will start missing also. Truck runs fine. Checked plugs wires, there is something I'm missing. Have a new oxygen sensor. Have also had the exhaust replaced. The catylitic converter had broken up and cloged exhaust. Thinking fuel problem or computer????? Help
