Why does my truck shudder when I take off?
Shaking or vibrating may be caused by many different things such as faulty spark plugs, poor fuel pressure or misfires. Other things such as a faulty idle air control valve may cause the engine idle to drop below the normal idling RPM which may also cause the motor to shake or vibrate more than normal.
Why does my truck vibrate when I accelerate?
Your vehicle’s engine and transmission send power to a differential and on to the wheels through a driveshaft. It rotates to transmit that power and torque, so a bend can cause major vibrations as you accelerate.
Can a leaking PCV valve cause rough idle?
a faulty pcv valve can cause a number of problems: 1. rough idle or stalling: if the plunger is stuck open, the pcv valve will allow too much air to enter the engine. this can cause a lean air-fuel mixture, resulting in a rough idle or stalling.
