Service Engine Soon + Vibrations. What's wrong with my car?

[Flipz]

Hi,

I was just on the hiway when my Service Engine Soon started appearing. Everything was running pretty good but when i moved on the street and started stopping there is this vibration like the car is shaking. The service engine soon sign doesn't stop blinking and this vibration stops after I accelerated and switch to 2-3 gear (I am on automatic transmission). I just parked the car and went to get a OBDII but Autozone are out . I am afraid of driving that car to the mechanic as he is 4 miles away and I do not want to break in the middle. There is this strange smell but it is not burned oil. The engine runs ok after I accelerate to 20mph+ but starts vibrating under that. Does anyone knows what can be the problem and whether I can take it to the mechanic or better tow it?

Thanks,

Svetlin

so its ok after 20mph? definately get the car scanned, you should be able to tell whats wrong with it then, no problem

There's no such light on a DSM, as they aren't Chevrolets.
Yes, when there is a question, always have it towed.
