I bought a Honda Civic Hatchback EG Automatic down in National City, The dealers told me it has been sitting for about 2 weeks so when me and my fiancee drove it off the lot to do a drive test, the motor is shaking alot even it gets worse when you are at a stop sign or a stop light I just got an oil change they checked everything and now they are telling I need a new motor. where can i go for to get a new motor for less??
