Just purchased 06 pure cdi. Turbo was replaced just before purchase. Have put about 2000 miles on it and I started receiving an intermittent engine check light. I have made an appointment at the nearest Smart dealer (Regina, CA) which is 200 miles north. In the meanwhile, yesterday I went to drive to a meeting and the car starts right up, however, when I apply fuel it shudders and hardly moves. I got it pointed downhill and then it ran fine down to my house where I parked it in the garage. Would this be an injector problem or clogged fuel filter? I've got a Monday appointment at the Smart dealer if I can get it there.
