1990 Mazda MX-6 mileage: 135,000. When trying to accelerate from a stop, the engine will lurch and shake violently. It is the worst when letting the clutch out into first gear, moderate into second gear, and above that it runs fine. The lurching isn't quite as bad if you accelerate slowly, but if you try to take off fast, it almost stalls out the engine. Help!
Replacing the clutch assembly and motor mounts should fix the problem. You should check the accordion-like rubber hose that connects the airflow sensor to the intake manifold. This hose develops cracks that allow extra air into the intake manifold when the engine shifts during acceleration, causing the car to lurch.
