I took the car (2000 Saturn LS Series) to Auto Zone and had the diagnostic run to find out the source of the problem but it did not help. I took it to the shop and he ran the same test and did not find the problem. He told me that sometimes when repair is done on the car that the computer was not reset and the computer still thinks there is a problem. So he reset the computer and told me to drive it around for a while and see if it solved the problem...No luck. I took it to another shop and he ran the same diagnostic test and found no problem...all codes were fine. He said sometime it could be bad gas. He advised me to add some " TUNE UP IN A BOTTLE" next time I had to gas up and this might help the problem. Well I bought the Tune Up in a bottle and it did still stall on me once. I'm not sure if it worked or not. I haven't driven it much. One other question...How do I check the transmission fluid??? I found the Trans Fluid knob but no dip-stick?

The 2000 Saturn models LS and LW are Saturn's first midsize cars,
In 2000, there was also a Saturn coupe, a subcompact sedan and a subcompact station wagon.Your car starting to run hot or can't starting ,maybe some wrong of the engine the battery or with something else. You can use a diagnostic check it at frist ,to find the tool ,on the obd2tool website.you will save some money and hassle.
When the security light comes on, it means that there is a failure in the anti theft system. It will either shut off the starter or turn off the injectors. The other lights being on are a result of the key being turned forward and the vehicle not running. If its 1998 or older, i know the security issue will not show up on a diagnostic machine. Especially if its at auto zone or some place like that. If the car doesnt run or start, and its on this list. Saturn
SW1/SW2I may have a solution for you. http://vatspasslockpasskeysecurityhelp.yolasite.com/ Bypassing is way cheaper than trying to fix these security systems.
When lit, the computer has found some type of problem with the engine computer system, often a bad sensor, or something electrical with the ignition, such as mis-fires, running rich/lean, etc. Auto Zone can find out why the light is on, by hooking up a OBD II diagnostic reader, to retrieve the code, that is associated with the paticular sensor.
many auto parts stores will run their diagnostic tool for you free .. that will narrow down the problem ... sometimes its just a loose or damaged gas cap (it has to seal in many cars) .. a bad oxygen sensor is a frequent cause as well .. (especially for a 9 year old car).. but any sensor can be bad or indicate a problem .. like vacuum leaks or misfiring or even low brake or tran fluid .. having it tested is a good starting point .. auto repair shops often charge for this service but auto parts stores do not .. you can call and ask .. the auto parts store will also likely have an service manual but sometimes are not very complete (look thru it before buying) .. your local library may have service manuals ..
This could be a faultyCKP ro CMP as well. you will need to run a diagnostic scan to actually receive the correct trouble codes in this case. the on and off cycle of the light will usually signal a miss in one or two of the cylinders.
I recommend taking this car to a local Auto Zone auto parts store. they will run a scan for free on your car. this scan will direct you to the actually part or issue that is causing your issues.
Idle problem most likey a Coolant Temp sensor & connector.Cam covers very common to leak around the sides & down into the spark plug holes.Also all saturn s-series 1.9 engine consume oil.Most 1qt. per 1500 miles some more some less.Service Engine Lamp has nothing to do with regular maintenance.It's a malfunction indicator lamp.If it's on there is Trouble codes stored in the ECM.Auto zone free scan with printout.Hope that helps
