I have a 93 Saturn sl2 that is surging 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 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
