Hi Darlene,

These engines can go well beyond 500,000 miles, and I know several people that can attest to that. There is one important thing you must know. ALWAYS check your oil at every gas fill up! Your SL2 is probably burning oil and needs to be checked. If you let it get too low you will spin bearings in the engine and it will be rendered useless. Check the oil and keep it at the top of the hatchmarks. It's a good idea to get two quarts of oil and leave them in the trunk this way you can fill as you need it.

The idle is probably the Idle Air Control valve (IAC). It is probably dirty and needs to be cleaned. Removing the throttle body and cleaning with carb cleaner to get the carbon off will get your idle working again. You cannot reset idles on these car and DO NOT touch the idle stop, that is not how idle is managed nor adjusted. The idle should be 1,200 RPMs cold and 800-850 warm.

Thanks,
Joe

SOURCE: '98 SL2 Saturn Traction Control

Traction control helps limit tire slip in acceleration on slippery surfaces. In the past you had to feather the gas pedal to prevent the drive wheels from spinning wildly on slippery pavement. Many of today's vehicles employ electronic controls to limit power delivery for the driver, eliminating wheel slip and helping the driver accelerate under control. Don't turn it off.

SOURCE: myservice engine light came today rogh in idle at light rpms seem a little high this is a 98 saturn sl2 I think engine is a 1.9

the check engine light means that a code has been set. the code will reference a faulty system that must be diagnosed and repaired. sorry for the vagueness, but there are e gads of codes that can cause the rough idling

most aftermarket parts places will scan the car for free. this will give you an idea of where to start.

SOURCE: saturn sl2 emissin problem

If the SES light is on, take a paper clip bend it in a u-shape and jump the scanner input positions A B. This should flash the ses in sequesces to give you the trouble code, Please see the following link. http://www.troublecodes.net/GM/ Refer to the code to see what the issue may be. SES lit means that there is a emmissions related issue. Refer to the other links for additonal information on O2 sensor resistance, and the egr valve solinoid. Check the EGR is relitive easy for operation. Remove the vaccum hose and place a hose of similar suckon the hose to pull vaccum if the diafram underneith retracts, hold the vaccum by plugging off the tube with your touge if the diafram retracts, will not hold the vaccum, it is bad. The solinoid should read 40-60 ohms if good. http://www.saturnfans.com/forums/index.php http://www.aldlcable.com/sc/pages.asp?pageid=21

I have a 98 Saturn SL2 with 230,000 miles. It runs great and gets almost 40 MPG highway. The only problem I have is that the idle speed varies from about 600 to 1700 RPMs as if I were revving the engine...


I would check the TPS (throttle position sensor) as that would cause a jump and decrease in idle when sitting in park, or in drive with foot on brake. Im not sure exacly where it is located on your car, but they are usually on the passenger side of the fuel injection system.

Just bought a 98 Saturn SL2 that is in excellent shape but high miles, mostly highway miles. It has 210,000 miles on it but was well taken care of and sounds and drives great. Had a new transmission put in...


yea it sounds like someone like most wanna be mechanics take a torques screwdriver and run the idle screw up on the throttle body instead of fixzing the real problem also you may want to concider testing and changeing the TPS

98 saturn Sc2 makes a helicopter sound in the front. Thought it was the tires replaced all 4 but it still makes the same sound. What could it be?


this isn't a solution, just a brainstorm of ideas
-front rotor? (brakes) this would cause lots of noise and viberation while braking over 50 mph
-it could be your belts?... if it makes the noise while the car is parked, and increases pace when you rev the engine.
-it also could be the cluch, (if standard tran) as that can make a high pitched chirping noise, but that is unlikely...
