When I start my car, it shakes extremely and continues when I put it in gear and drive up to about 20 mph.
It levels out and doesn’t shake at 30 + mph.
An Engine Service light comes on sometimes, but that has to do with emissions and I don’t think this is an emissions problem.
Any ideas and how much for repairs?
It is possible that fuel is not being delivered or at least not being mixed with air properly at lower speeds. Check with a dealer for injector build up and/or mixture problems.
