★ Top Answer
If your 2012 Ford Fusion is making engine noise, it could be caused by various factors. One common issue is a loose bolt in the engine mount, causing vibration during operation. Another possibility is a problem with the air intake manifold or the idle air control if the engine shakes when idling. This could indicate an incorrect air-to-fuel ratio and difficulties in combustion. Additionally, issues with the fuel injection system or fuel pump can also lead to shaking due to insufficient fuel supply. These concerns are significant and must be resolved, with the cost varying based on the specific problem.
