Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hello. Welcome to Just Answer. Please allow me to assist you. If you have a random low RPM misfire, and the electronics are all good and new, the fact that you mention it is burning oil may be the issue. If the oil control piston rings are seized (common on a 16 year old car), I would recommend that you change to a high mileage motor oil, and then get 2 cans of a fuel injection cleaning product known as BG 44-K. This is kind of hard to find but the BG website has a screen where you type your zipcode in and it will tell you where the nearest vendor of this product is. Get a can of the BG 44 K and pour it into the tank. Top the tank off to 3/4 full and drive it, running the tank to 1/4 as fast as you can (the product loses strength if it sits. Then repeat with the other can. The high mileage oil will soften the valve seals and lessen oil dripping down the intake valves into the cylinders. The BG 44K will clean deposits off of the valve faces and clean the injectors. It will also assist in loosing the carbon that is causing the oil control rings to be seized up. Change the high mileage motor oil every 3,000 miles. This should lessen your oil burning and cause the running rich to lower. This is exactly what we would be doing if your vehicle was in our shop. We would not be changing TPS or things like that if there was not failure code for the TPS, etc.
