***MUST READ***
Hi guys here's a DIY guide on how to clean your injector nozzles if they're clogged or if you simply want to add this method in your routine maintenance. We recommend cleaning the nozzles every 100,000kms and while you're at it, replace the injector O-rings and Copper washers with new ones as well. It's also best to clean the injector seats on the cylinder head before you put the injectors back in. There are injector seat cutter tools which you can purchase online.
Remember: This is not a certain fix on faulty injectors. If your injector is stuck open / closed, doesn't fire or actuate when energized, excessive back leakage, It's best to consult a professional.
