I am having engine surge under light load at 30-50 mph It does not do it while acelerationing only holding steady speed. I have replaced the fuel cap, fuel filter spark plugs and wires and checked air filter nothing has changed The car has ben serviced at precribed intervals using mobil 1 syntetic oil. It does not burn oil and outside of this problem the engine runs fine
