I have a 93 Saturn sl2 that is surging <or more accurately momentarily loosing acceleration> at while at constant speeds. it will occur in any gear but seems to be more prominent in the lower gears. I have recently replaced the spark plugs, throttle position sensor, and coolant temp sensor: and switched out the EGR valve <with another used one> to alleviate a stalling problem at idle. there are no engine codes being stored. any suggestions on what might be the cause and possible solutions? thanks for your time kallita
