miles. I bought the car for 4 years. In Feburary.One time when I
was driving, I felt the engine shake when I stop at the red
light, and later the car at 10 MPH, the engine shake again and
the car stop running. So my friend help me to change the spark
plugs, PCV valve, rotor. The car run normal again.  In April
10th, the engine shake again, and the car stop running, and
won't start again. So my friend help me the change the

seconds. I could start the car, when the car is in parking
