Hello and thank you for using just answer. What kind of saturn is this? A SL or a SL2? If not sure then open the hood, it the top of the egine a black plastic cover or a silver aluminum cover?
How many miles are on the car?
Is the check engine light on?
Once the car runs for a while does it clear up or have you not run the car long enought to tell?
It has a black cover on it
It was then went out
At first it did, but now no
THank you for the reply. This would be best if you connected a scan tool to check the codes, if you don't have access to one then consider an auto parts store, most now offer a free code check, rent scanners cheaply or sell them starting around $40.
You need to check for vaccum leaks around the intake manifold, the pcv hose area and throttle body.
Most likely you have a sticking idle control issue here or more commonly the coolant temperature sensor has a crank in it and is sending false signal to the ECM resulting in fuel mixture issues and your symptoms.
