For about 1 month now my 1992 Saturn SL1 "Service Engine" Light comes on but goes off about .5 miles down the road. Only in the morning though. I have noticed in my other vehicle, a 1996 Mercury Villager, this is when the van is warm enough for heat, so could it be something with the temperature of the car? I cannot take it to get checked because the light does not come on any other time. Should I start with flushing the radiator? Thanks for any advice
Any time that light comes on, it is stored in the computer. When ever that light comes on, it means that there is something wrong that needs to be looked at. Now, since the light goes off, that means that it is not something fatal. I would hook up a code scanner and see what codes are being set before making any further considerations.
