Burning oil? Failed cylinder seals. More then three quarts a month, ditch the car. One quart or less isn't too bad. In that case you will need to keep an eye on the EGR valve nad possibly the O2 sensor (if your 94 has one) past the exhaust manifold. What's happening is that oil is entering the combustion chamber and ignighting with the fuel air mixture. The result is exhaust gas much more laden with soot. This soot can wear down spark plugs faster and thus the coil packs faster too. This soot covers everything and fouls up the EGR. If your engine decides to rev up on its own, a good bet your EGR has failed. Bottom line, less than a quart a month, remove the EGR every six weeks and soak the bottom in carb cleaner. Change spark plugs every six months. Autolites are cheap at wal-mart. The body on your Saturn is probably perfect, but a 16 year old Saturn motor isn't worth replacing the seals on.
