What to Do About Engine Surging?

[MacLayla]

Issues with the spark plugs, high-voltage wires, and ignition coil can lead to poor performance of the ignition system. Check if the spark plugs are excessively carbon-fouled and replace them if necessary. Abnormal fuel pump supply pressure or incorrect readings from the intake pressure sensor can cause engine shaking. In this case, check the fuel pressure and replace components if needed.
