This is my wife's daily driver. It has an auto trans, 4 cyl engine, 2 wheel drive, 140K miles.
About two weeks ago I noticed when driving, the car has a slight 'jerking' feel to it. I noticed it again today just a few minutes after leaving my house on the way to the gas station. We haven't drove the car at all today so the transmission wasn't hot and the engine had not reached normal operating temperature yet. I got to the station, filled her up, and headed home. As I was driving I felt the car jerk again. It's just a slight jerk though, nothing crazy. It happens like twice a minute on idle driving and it happens on acceleration and deceleration almost every time.
Other things the car is doing that it didn't used to do. things happened gradually as the miles and age of vehicle went up (not sure if related to above issue):
- acceleration performance has declined.
- after starting and idling engine, the car kinda vibrates a little
- gas mileage has gone down a little.
I appreciate all comments and feedback.
