Re: 98 Saturn SL 1 sputters
Have a scanner hooked up to your car and do a data stream to see if your knock sensor is still working. On a heavy load, if the ECM detects detenation in the engine, it will automatically want to ****** the timing to make it run better on a load.

Saturn i think this is the same car or the same engine and software type as our opel vectra /zafiro range and if so then these cars from this age are notorious for dodgy ECUs ,the faults are varied but basicly the same but this one is only the idle and no fault lights on so i would suspect a FAULTY STEEPER MOTOR so renew this first and see what happens if that doesnt work then consult a local mechanic with saturn experiance
my car is a 2002 saturn sl1 i was woundering if you can help me with my car when i drive on the freeway up hills my car goes from fast to slow so i have to shift from 5th gear to 2nd or 3rd gear and i have to go like 40 mph on a 65 mph speed limit all the way home how do i fix that problem
take the console out and look under the shifter, if the shifter cables are disconnected from the shifter go to a parts store or ebay and get yourself a Saturn shifter bushing repair kit. happens all the time to S Saturns and maybe the Ls look on youtube for instructions to remove console and put on the bushing kit.
if the shifter cables are still connected you may have to be looking around for a lower mileage used transmission. 96-98 saturn will fit so long as the donor car has the same head, being DOHC or SOHC. so if you have an SL1 you can use a transmission out of another SL1, or an SC1, or an SW1. do not mix a 2 with a 1, bad mojo.
Fuel comes in different grades due to octane levels, the higher grade the higher octane, the higher price. If you have the owners manual or window sticker, you would see that the car was probably made to run on 87 octane (regular unleaded), I have been through the different octane levels for more than 30 years and I have decided that the cheapest runs as well as the most expensive. The higher octane will sometimes cause an engine to ping or rattle under acceleration, if this happens to yours go back to the cheap stuff and everything will be fine. That is my opinion, others may differ, but I run my BMW on the cheapest I can find and I still get 31 MPG hwy.
