What Causes Engine Shaking During Cold Morning Starts?

Engine shaking can be caused by excessive carbon deposits, fuel system malfunctions, or cylinder misfires. Here are detailed explanations: Excessive Carbon Deposits: Severe carbon buildup in engine cylinders can lead to spark plug clogging and valve blockage, directly resulting in vehicle shaking during idle. Fuel System Malfunction: Unstable fuel pressure may cause inconsistent air-fuel mixture concentration, resulting in both shaking and unstable idle. First consider replacing the fuel filter, as prolonged use may cause clogging. Then check fuel pressure bypassing the filter - abnormal readings may indicate fuel pump issues. Cylinder Misfires: If ignition coils malfunction or spark plugs fail to fire properly for any reason, the vehicle will exhibit shaking symptoms.
