Drive gently and get it diagnosed within days.
Shaking under acceleration usually means the engine is misfiring under load, or something in the drivetrain (mounts, CV joints) is worn. Note WHEN it shakes — only while accelerating points to engine/drivetrain; while braking points to rotors.
Misfires under load are the top cause of shaking when accelerating.
The engine physically moves — shaking felt in the cabin.
Fuel starvation under load.
Shaking that worsens with speed and acceleration.
Shaking specifically when braking from speed.
Typically $100–$800
Plugs/coils typically $100–$400; engine mounts typically $200–$600; CV axle typically $300–$800. Estimates vary by vehicle. Costs are estimates and vary by vehicle, location, and shop.
Shaking under acceleration usually means the engine is misfiring under load, or something in the drivetrain (mounts, CV joints) is worn. Note WHEN it shakes — only while accelerating points to engine/drivetrain; while braking points to rotors.
If shaking is violent or the check engine light flashes, stop — you may be damaging the catalytic converter. Otherwise, get it diagnosed within days.
