What are the symptoms of a bad camshaft?

The symptoms of a bad camshaft include difficulty in ignition, hard starting, unstable idle, inability to accelerate, weak engine power, car shaking, persistent illumination of the malfunction indicator light, sudden stalling when the engine is hot, jerky driving, and accelerated engine wear. The camshaft is a component in a piston engine, and its function is to control the opening and closing of the valves. The main body of the camshaft is a cylindrical rod approximately the same length as the cylinder bank, with several cams attached to it for driving the valves. The camshaft is supported within the camshaft bearing bore by camshaft journals, so the number of camshaft journals is an important factor affecting the support stiffness of the camshaft.
