Ignition system problems
Worn-out spark plugs, ignition wires, or distributor components can cause misfires and poor engine performance.
Vacuum leaks
Cracked or disconnected vacuum hoses can lead to rough idling and poor acceleration.
Exhaust manifold cracks
The exhaust manifold can develop cracks over time, leading to exhaust leaks and increased engine noise.
Idle control valve failure
A faulty idle control valve can cause irregular engine idling and stalling.
