Problems:

Oil leaks
Common in aging gaskets and seals, particularly around the oil pan and valve covers.
Supercharger issues
The supercharger might develop bearing noise or even failure due to wear and tear.
Intake manifold gasket failure
The plastic intake manifold gaskets can degrade over time, leading to coolant leaks and engine overheating.
Crankshaft position sensor failure
This sensor is prone to malfunction, causing the engine to stall or not start.
Ignition coil pack failure
These can fail over time, leading to misfires and rough engine operation.
Transmission problems
The transmission can suffer from shifting issues or failure, especially in high-mileage vehicles.
Fuel injector issues
Build-up in the fuel injectors can cause rough idling, poor acceleration, and reduced fuel efficiency.
Cooling system failures
Common issues with the radiator, water pump, or thermostat can lead to overheating.
Vacuum leaks
Aging vacuum lines can crack, leading to performance issues and poor fuel economy.
Throttle position sensor failure
A faulty throttle position sensor can cause erratic idling and poor acceleration.
Egr valve problems
The Exhaust Gas Recirculation valve can get clogged, leading to reduced engine performance and increased emissions.
