Disadvantages of the HR12DE engine
Although people frequently complain about excessive vibrations on the forums, this motor is dependable;
Contamination of the throttle or injector is the primary cause of floating speed;
The mass air flow sensor rapidly malfunctions when using a cheap air filter;
The fuel pump in the tank and the ignition unit relay are the engine’s weak points;
Additionally, since there are no hydraulic lifters here, remember to adjust the valve clearances.
