Turbocharged engines like the one in the 1991 Ford Probe can experience oil leaks due to increased pressure and heat, which can cause seals and gaskets to fail.

The turbocharger can wear out over time due to high operating temperatures and pressures, leading to reduced performance or failure.

EFI systems can develop problems with sensors, injectors, or the control module, leading to poor engine performance or starting issues.

Turbocharged and intercooled engines can be prone to overheating if the cooling system is not well-maintained or if there is a failure in the intercooler.

High pressures from turbocharging can cause head gasket failure, leading to coolant and oil mixing or loss of compression.

In-line 4-cylinder engines can experience wear in the timing belt or chain, which could lead to timing issues or engine damage if not replaced at recommended intervals.

Components like spark plugs, ignition coils, and wires can wear out, causing misfires or poor engine performance.

Turbocharged engines have complex vacuum systems that can develop leaks, leading to poor engine performance and fuel efficiency.

The intercooler can become clogged or damaged, reducing its effectiveness and potentially leading to engine overheating or loss of power.

Common in older vehicles, oil leaks can occur around the valve cover, oil pan, or seals.

Due to age and wear, the cooling system may become less efficient, leading to overheating.

The timing belt may degrade over time and could break if not replaced at recommended intervals.

EFI systems can suffer from clogged or malfunctioning fuel injectors, leading to poor engine performance.

Components like spark plugs, ignition coils, or distributor may wear out, causing misfires or poor engine performance.

Hoses and gaskets can deteriorate, leading to vacuum leaks that affect engine performance and fuel efficiency.

The 1992 Ford Escort with a 4-cylinder Mazda engine can suffer from overheating due to a faulty thermostat, clogged radiator, or failing water pump.

The in-line 4-cylinder engine may experience timing belt issues, which can lead to engine misfires or severe engine damage if not replaced at recommended intervals.

The Electronic Fuel Injection (EFI) system might have issues like clogged or leaking fuel injectors, leading to poor fuel economy and engine performance.

Common in older models, oil leaks can occur from the valve cover gasket, oil pan gasket, or crankshaft seals, potentially leading to low oil levels and engine damage.

Problems with the ignition coils, spark plugs, or distributor can cause misfires, rough idling, and starting difficulties.

Vacuum hoses and gaskets can deteriorate over time, leading to leaks that affect engine performance and cause rough running or stalling.

Issues such as a failing catalytic converter or exhaust manifold leaks can lead to poor engine performance and increased emissions.

Common in older engines, often due to worn gaskets or seals.

Can wear out or break, leading to engine damage if not replaced according to schedule.

Turbocharged engines can suffer from turbo lag, wear, and eventual failure.

EFI systems can have clogged or malfunctioning fuel injectors, affecting performance.

Turbocharged engines are prone to head gasket issues due to higher pressures.

Problems with spark plugs, ignition coils, or distributor can cause misfires and poor performance.

Turbocharged engines generate more heat, leading to potential overheating if the cooling system is not maintained.

Can occur in the intake manifold or related hoses, causing rough idling and poor performance.

EFI systems rely on various sensors (like the oxygen sensor) that can fail over time, affecting fuel efficiency and emissions.
