Problems:

Overheating
The 5M-GE engine, like many older engines, may have cooling system issues such as a failing thermostat, water pump, or clogged radiator, which can lead to overheating.
Oil leaks
Gaskets and seals in older engines like the 5M-GE can deteriorate over time, leading to oil leaks, particularly from the valve cover gasket, oil pan gasket, and rear main seal.
Fuel injector problems
The electronic fuel injection system can suffer from clogged or malfunctioning fuel injectors, leading to poor engine performance and reduced fuel efficiency.
Timing belt wear
The 5M-GE engine uses a timing belt that can wear out and may need regular replacement to avoid engine damage.
Ignition system issues
Problems with the ignition system, such as worn-out spark plugs, distributor cap, and rotor, can cause misfires and poor engine performance.
Vacuum leaks
Vacuum hoses and connections can become brittle and crack over time, leading to vacuum leaks that can cause rough idling and poor acceleration.
Head gasket failure
An older engine like the 5M-GE may develop head gasket issues, leading to coolant mixing with oil or compression loss between cylinders.
Egr valve issues
The Exhaust Gas Recirculation (EGR) valve can become clogged or fail, causing increased emissions and poor engine performance.
Sensor failures
Various sensors, including the oxygen sensor, coolant temperature sensor, and mass air flow sensor, can fail or provide inaccurate readings, leading to engine performance issues.
