In the event the fuel force is simply too superior, the engine will not likely operate adequately, fuel are going to be squandered, and contamination will likely have appeared from the fuel.
Maintain stress can leak down on account of a leaking injector, but That is a relatively gradual leak. If maintain force leaks down promptly following the motor is switched off, that’s a foul Look at valve.
