Problems:
Brake fluid leak
Hydraulic brake systems rely on brake fluid to transmit force from the brake pedal to the brakes themselves. Leaks can lead to a loss of braking power and increased stopping distances.
Brake pedal feels spongy
This can be caused by air bubbles trapped in the brake lines, which can reduce the effectiveness of the braking system. Bleeding the brakes can resolve this issue.
Brake pads and rotors wear
Over time, brake pads and rotors will wear down and need to be replaced. Worn brake pads can lead to reduced braking performance and increased stopping distances.
Engine misfires
An in-line 4-cylinder engine can experience misfires due to various reasons including spark plug issues, faulty ignition coils, or problems with the fuel delivery system.
Cooling system problems
The engine can overheat if there are issues with the radiator, water pump, or thermostat. Overheating can lead to severe engine damage if not addressed.
Oil leaks
Common in older vehicles, oil leaks can originate from various points such as the valve cover gasket, oil pan gasket, or rear main seal.
Timing chain/belt issues
If the timing chain or belt is worn or damaged, it can lead to poor engine performance, misfires, or even engine failure if it breaks.
Fuel injector problems
Faulty or clogged fuel injectors can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
Vacuum leaks
Vacuum leaks can cause the engine to run lean, leading to rough idling, poor acceleration, and increased fuel consumption.
Check engine light (cel) issues
Various sensors and components can trigger the CEL, indicating issues that range from minor to severe. Common causes include faulty oxygen sensors, catalytic converter issues, or mass air flow (MAF) sensor problems.
Throttle position sensor failure
This sensor monitors the position of the throttle and can cause erratic engine behavior if it fails, such as stalling or poor acceleration.
Electrical problems
Older vehicles like the 2002 Jeep Wrangler can experience issues with wiring, connectors, and relays, leading to intermittent electrical faults or failures in systems such as the lighting or starting system.
