What Causes the Odyssey to Shake at 40 MPH?
1 Answers
There are several reasons why the Odyssey may shake at 40 MPH: Severe Engine Carbon Buildup: The most common cause of car shaking is a dirty throttle body or excessive carbon deposits on the fuel injectors. Solution: Clean the fuel system and check if the idle control valve has carbon buildup that needs cleaning. It is recommended to use BOD's "Fuel System Cleaner," which can be added to the fuel tank during refueling to clean the fuel system. Ignition System Issues: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or weak spark plug firing can also cause such issues. Solution: Inspect the spark plugs for excessive carbon buildup and replace them if necessary. Unstable Fuel Pressure: It is advisable to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor. Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor can lead to vehicle shaking. Solution: Check the fuel pressure and replace components if necessary.
