Question about 2000 Saturn SL
Sounds like your AIC air idle control. It's attached to your throttle body. If you take off the throttlebody [2 10mm bolts ] you can check and clean the AIC. It comes off the TB with 2 torx screws. When you get it off, clean the plunger with brake cleaner and clean the TB front and back. The back may have carbon build up. Scrape off and spray down. Replace the opposite way. This only takes 30 minutes so its worth the checking. If car still runs rough, spray the brake cleaner directly onto the intake manifold gasket while it's running. If the car changes in idol at all, the gasket is shot. Concentrate on cylinder 1 and 2. This is the area beside the power steering pump. Spray it good while listening. Also spray the vacuum hoses that go up to the intake. If there is any leaks this is the way to find them.. The onlt other thing I can think of is a weak coil, but I think you will find the problem with the brake cleaner. Let me know how you make out. Cheers from Nova Scotia!

Keep it simple.
Check for vacuum leak at inlet manifold......at idle simply spray some crc lube or similar (Brakleen is very good) around manifold and listen for increase in reves. If so leaking manifold gasket or similar.

The problem here is the ECTS. Engine Coolant Temp. Sensor. It cost around $12 dollars and takes maybe 5 mins to fix with a 13mm socket. Saturn SL series built before november 2001 have a plastic ECTS. When you buy the new one make sure it has the brass tip as some parts stores still carry the cheap plastic one

Testimonial: "That was the problem. I called the dealer and thats what they told me. It runs great. I had to get a 13mm deep socket . $20 tool, $12 part. Thanx"
MASTER CYLINDER SHOULD BE BENCH BLED BEFORE INSTALATION.PUT MASTER CYL. IN VISE-SHOULD HAVE COME W/RUBBER TUBES & ADAPTERS TO CURCULATE FLUID FULL STROKE OF CYL. TILL ALL AIR BUBBLES ARE GONE.THEN INSTALL MSTR CYL./GETT SOMEONE TO PUMP BRAKES THEN HOLD PEDAL FIRMLY WHILE YOU RELEASE BLEEDER VALVES ONE AT THE TIME FARTHEREST FROM THE MSTR CYL. TILL ALL AIR IS PURGED. REPEAT STEPS TO EACH BLEEDER TILL ALL HAVE BEEN DONE.GOOD LUCK W/THAT!
