crank it up and pull one of the battery cables off and if it cuts off it's the alternator.

Check fuses next, best done with a meter or a test light. You have a panel to the right of the center console in the front where the passengers left foot is, There is also one under the hood by the left headlight area. Remember that fuses for lights are only powered with the light switch on.

For old models, Saturn/GM also used the same material fiberglass gasket in your model, you almost certainly have a leak from a crumpled, sucked-in gasket as I suffered (and many others). I would say going to Saturn dealership to make repairs is probably not good idea if they are going to put in the same GM intake gasket part. Maybe possible to specify Felpro gasket with whatever shop you go to if you don't do the repair yourself. I would not go too long with your car in that condition as there is localized leaning at your cyl-3, that could cause a burnt exhaust valve there.

The exhaust is extra hot venting out that cylinder. P0303 is misfire at cyl-3. Mine was P0301 (cyl-1). You may get P0507 once in a while when PCM fails to control the fast idle caused by the leak under certain conditions. Most of the time, it is very slow idle caused by 3 cylinders running. You run smoother in cold idle because the IAC opens up to increase idle and end up lowering the manifold vacuum, so the reduced vacuum causes less leaking at the failing intake manifold gasket.

I'd say try cleaning everything with your ignition before replacement; Idle problems could be caused by engine coolant sensor (ECTS). Are you sure it was changed? Did they put on a new wire connector along with it?

Hope helps.

saturs have always had problems with the taillights not working or signals not working also, the way i was told to fix the problem is to change the plugs where the bulbs go, the plugs get burn spots and wont let the bulbs make contact. hope this helps.
