Running lean usually refers to a condition where insufficient fuel reaches the combustion chamber. A clogged fuel filter could cause this. Swap it out for a new one before you ruin your spark plugs or, even worse, a fuel pump. Also, vacuum leaks can cause this condition. Go ahead and change the fuel filter since they are cheap and you will need to soon enough anyway. But, I think a vacuum leak is a more probable cause. Mention your car and engine type for better answers.

Fuel pressure on Honda CRX is running too lean how do I correct?
If your Honda CRX is running too lean, you can address the issue by checking and adjusting the fuel pressure. Start by inspecting the fuel pump, fuel filter, and fuel injectors for any clogs or malfunctions. If those components are functioning properly, you may need to adjust the fuel pressure regulator to ensure it provides adequate pressure. Additionally, consider checking for vacuum leaks and ensuring that the engine management system is functioning correctly, as these factors can also contribute to a lean condition.
