Q3 How do I replace the fuel filter in a 2002-2004 Infiniti I35?
How do I replace the fuel filter in a 2002-2004 Infiniti I35?
To replace the fuel filter, first, relieve the fuel system pressure by disconnecting the fuel pump fuse and running the engine until it stalls. Locate the fuel filter, typically near the fuel tank. Disconnect the fuel lines and remove the old filter. Install the new filter, ensuring the flow arrow points toward the engine. Reconnect the fuel lines and the fuel pump fuse, then start the engine to check for leaks.
Q4 What should I do if my Infiniti I35 experiences poor fuel economy?
What should I do if my Infiniti I35 experiences poor fuel economy?
Poor fuel economy can result from clogged fuel injectors, a dirty air filter, or incorrect tire pressure. Start by checking and replacing the air filter if necessary. Inspect tire pressure and adjust it to the recommended level. Use a fuel injector cleaner or have the injectors professionally cleaned. If issues persist, scan for diagnostic trouble codes to identify potential engine or sensor problems.
Q5 How can I optimize the fuel performance of my Infiniti I35?
How can I optimize the fuel performance of my Infiniti I35?
To optimize fuel performance, use premium unleaded gasoline as recommended. Regularly replace the air filter and spark plugs, and ensure proper tire inflation.
