I bought a used car just 3 weeks ago. After 2 or 3 days of purchasing the car, car started shaking on driving. Once the car had sign of engine and stopped, was moving to mechanic by a tow truck. The mechanic changed 4 spark plugs and it was pretty good for a few days, however, it start shaking a bit. The mechanic said it would be a piston ring problem. When he scanned the car, the compression was low in second cylinder and the spark plug was with oil. I don't know about a car at all and I'm in panic now. Please give me some information about what I should do. Thank you.
have the same problem?
