I WAS DRIVING ON THE FREEWAY WHEN MY ENGINE LIGHT COMES ON, WHEN I PURCHASED 1990 LS400 THE PREVIOUS OWNER JUST RECENTLY CHANGE THE OIL, THE NEXT OIL CHANGE IS 189500, THEN CHECK ENGINE LIGHT COME ON AROUND 189100, SO I CHANGE THE OIL AND RESET THE COMPUTER, BY THE WAY I STARTED USING SYNTHETIC OIL, PENSOIL PLATINUM 10-30, SO THE ENGINE LIGHT DID NOT COME ON FOR ABOUT 3-4 DAYS, I WAS DRIVING ON THE FREEWAY WHEN THE ENGINE LIGHT COMES ON (77-80 MPH), I RELEASE THE GAS TO SLOW DOWN FOR A LITTLE BIT THEN THE LIGHT GOES OFF, I ADDED MORE OIL TO TOP IT OFF, CO'Z THE MANUAL SUGGEST IT MAY BE LACKING OIL, IS THERE ANOTHER PROBLEM THAT CAUSE MY ENGINE LIGHT TO COME ON?
