Most common problems:

Brake fluid leaks

Hydraulic brake systems can develop leaks in brake lines, master cylinders, or wheel cylinders, leading to reduced braking performance.

Brake fade

Overheating of the brake components can cause the brakes to become less effective, especially during prolonged or heavy braking.

Warped brake rotors

Heat and stress can cause brake rotors to warp, leading to vibrations and reduced braking efficiency.

Engine overheating

V-shaped engines, especially older ones like in a 1991 model, can suffer from cooling system issues, leading to overheating.

Oil leaks

Older V8 engines are prone to developing oil leaks from seals and gaskets.

Ignition system problems

The ignition system components such as spark plugs, wires, and distributor can wear out, leading to misfires or poor engine performance.

Fuel system issues

LPG conversions may introduce complexities and potential issues with fuel delivery and engine tuning.

Exhaust manifold leaks

V8 engines can develop cracks or leaks in the exhaust manifold, causing noise and potential emission issues.

Timing chain/belt wear

Over time, the timing chain or belt can wear out, leading to potential engine timing issues.

Sensor failures

Older vehicles may experience failures in various sensors, such as oxygen sensors, affecting engine performance and fuel efficiency.
