My 1999 saturn sl had a blown fuel pump fuse, and now after fixing the problem, the rpms are too high and not idle properly.

SOURCE: 1999 Saturn SL2 DOHC Engine - Fuel pump not pumping fuel.

The Saturn Fuel pump relay and fuse is located undar the panes on the passenger side of the center console near the passengers left foot there are two relays there that look identical one is fuel pump relay. Just switch them around they are bot the same and see if the fuel pump runs now also the fuel pump fuse is in there i can't send diaagrams on fixya because their program will not let them go through if you need one email me at [email protected] Please give me a fixya rating if this information is helpful to you

Intake manifold gasket. Leaking where intake meets head.

Clean the Idle Air Control Valve. It's on the throttle body below the Throttle Position Sensor. Worked for me! Good luck.

SOURCE: Saturn 1999 sl Engine has a high idle speed.

The Idle Air Control valve is located on the throttle body. If you follow the intake tube from your air filter all the way back to the intake manifold, where the intake tube connects to is the throttle body. Remove the intake tubing and you can see the throttle body.

There are two sensors on the throttle body and a vacuum line. You'll see two harnesses going to the throttle body, one is the IAC.

However, a quick diagnostic check can be done without touching the throttle body to confirm your problem. If the car has a normal idle when initially started but then rises to a higher idle and stays there BUT then if you were to shut the car off and restart it and it comes back to normal that is the Throttle Position Sensor (TPS). This is also located on the throttle body (the other sensor to the IAC). If it is the IAC it will be high and maybe fluctuate a bit.

Testimonial: "I was the one who listed this problem. Thanks a TON for the info. Now, I'll try to fix it. The ultimate check is if if idles normally."

SOURCE: fuse box diagram for 1998 saturn sl

There is an interior fuse panel just to the left of the passenger's left knee. The cover It is held on by velcro. After you take off the cover, you will see a diagram on the inside of the cover telling you which fuse is for what. This is covered in your manual, which is in the glovebox. If you do not have a manual you can get one off ebay for a few bucks.
