I have a 2002 Saturn L100. My service engine light went on. I changed the spark plugs. Which were bad. Thought that would fix the motor to stop shaking. It stopped alittle. But now they said I have a pressure leak that is why the idle is also off. How do I find out we're the leak is coming from. Can I do it myself. Can't afford to take to a shop.
