My 93 Saturn SL2 hesitates under light acceleration and surges a bit when giving it just enought throttle to maintain a steady speed. I replaced the temp sensor, plugs, wires, cleaned the coil tips where the wires go on, and took the egr off to clean it. I still have the same problem. It run quite well otherwise, starts easy & idles fairly smooth. Any suggestions?
