Engine misfire
The in-line configuration can sometimes lead to uneven fuel distribution, causing misfires.
Turbocharger (tc) issues
Turbochargers can suffer from lag, overboost, or mechanical failure, affecting engine performance.
Fuel injector problems
Direct fuel injection (DFI) systems are prone to clogging or failure, leading to poor fuel economy and performance.
Cooling system failures
The engine's high performance can put strain on the cooling system, leading to overheating issues.
Timing chain or belt wear
High-performance engines can experience accelerated wear on timing chains or belts, leading to potential engine damage.
Electronic control unit (ecu) faults
Modern engines rely heavily on ECU for management, and faults can lead to various performance issues.
Carbon build-up
Direct injection engines can suffer from carbon build-up on intake valves, leading to reduced efficiency and power.
Transmission issues
High torque from the engine can put stress on the transmission, leading to wear or failure.
Oil leaks
High-performance engines are often more prone to oil leaks, especially around the turbocharger and seals.
