Idle fluctuation
Problems with the idle air control valve or throttle position sensor can lead to unstable or fluctuating idle speeds.
Fuel injector issues
The electronic fuel injection system can suffer from clogged or malfunctioning injectors, leading to poor performance and fuel economy.
Ignition system problems
Issues with the ignition coil, distributor, or spark plugs can cause misfires, rough running, and reduced power.
Vacuum leaks
The age of the vehicle can lead to cracked or brittle vacuum hoses, causing vacuum leaks that can affect engine performance and efficiency.
Sensor failures
Components like the coolant temperature sensor or oxygen sensor can fail over time, leading to incorrect readings and poor engine management.
Exhaust manifold cracks
The exhaust manifold can develop cracks, particularly due to heat cycling, leading to exhaust leaks and potential loss of power.
Engine mount wear
The transverse mounted engine can cause more wear on engine mounts, leading to increased vibration and noise.
