Saturn starting problems

u should check the specs on the coolant sensor & ck for vacuum leaks. When u step on the "gas" u are really controlling the air intake, the fuel injection is controlling the fuel. A bad coolant sensor or vac leak will give u these problems also. ck emissions when running. Good luck

How can you turn down the idel car runs wayto fast.

You will need to play with the idle air control motor or adjust the throttle cable. Lots of times when the vehicle idles to high there is a vacum leak or broken rubber hose sucking in excessive air. To find it you can take throttle body cleaner and spray under hood. If the idle bogs down then you know you have a vacum leak that needs to be repaired.

Car is ideling at 2 grand in park

You probably have a vacuum leak, Lift the hood and listen for a whistle noise. It could be a hose that has rotted and is leaking , the PCV valve is bad, or maybe even upper intake gasket leak. pretty good chance of a vacuum leak, thats what 9 times out of 10 causes high idle. Hope this helps ya.. Cobra :-)

Rough idle then stalls

Vacume leak or bad idle motor. With the car in park and running with the hood open listen for leaks moving your hand around the different hoses looking for a change in the sounds that you hear. The idel motor also makes the car idel up to 1500 RPM or so right at start-up then idel down, If it doesn;t the idel motor is likly. Check engine light is on when running? Test for codes, Follow code test charts don't skip any steps!.

Your automatic choke is probably sticking. Spray it out with 2+2 Carb and Choke Cleaner. Do this when the car is cold so you don't start a fire. While the car is running see what position the choke butterfly is in when the engine is hot. If it is partially closed you may have a bad spring in the choke mechanism or it may need an adjustment.
