Question about 2000 Subaru Outback
2000 Subaru Legacy Outback has shut off twice while driving (engine stopped and dashlights came on), both times with the clutch engaged to stop. Idling rpm around 250 instead of normal~750. The check engine light revealed a p0325 knock sensor error that has existed for longer than these symptoms have occurred. The car will sometimes smell of gas when warming up on cold days and just after starting rpm have reached 1500. I cleaned the battery terminals and also checked the coolant which was normal.

Best thing to do in your case is take it to a mechanic and put it on a computer scanner to bring up a code # to detect the faulty part. The Check Engine Light usually represents a problem in the emissions system.

Erratic idle is often due to a vacuum or air leak in one of the engine systems, or faulty sensors sending incorrect data to your engine's computer.
As your vehicle is OBD-II compliant (ie has OnBoard Diagnostics) your engine computer will have stored the appropriate fault codes.
Before you start changing any components, always have the codes extracted from your onboard computer as this process will quickly identify which circuit (or sensor) is causing this condition. Changing your TPS may have been unneccessary.

Sounds like changing the belt had nothing to do with the problem unless something was disconnected or damaged. Maybe you already know all the problem codes, but if not here is a list of them. Also, when you make a reapair on one of the codes you have to reset the codes. They stay in memory until you rested them. So if you reset the 336 and 341 codes my disappear. Reseting the codes doesn't have anything to do with not starting. Make sure nothing was accidentaly disconnected or damaged. The throttle sensor is on the throttle which is in the housing that the air cleaner connectes with. I'm unsure where the Knock sensor is located. The catalyst sensor is probably one of the oxygen sensors in the exhaust pipes, the farthest away from the engine. Your discription of how the care died sounds to me like the throttle sensor.
The problem you have withour having someone check all these item with a system scanner, is you don't know which is defective or if they all are. When you purchase any of these sensors, they are expensive and they are not returnable once you open the packaging. If it not a connection or broken item that is ovbious, I recommend you have a quilified shop check the problem. Guessing can cost a lot for no reason.
