Meister Werks now offers fuel injector cleaning and testing with our new Launch CNC-602a injector tester. This machine can test any range of RPM, leak test, spray pattern and many more. It can also do ultrasonic cleaning and back flush the injector to get 100% of all contaminants out of the injector.
How it works:
We install the injectors into the machine and do an auto test. This tests spray pattern, idle speed spray at 650 RPM, 4500 rpm and 6000 RPM. Furthermore, this test alone, we can determine wether or not the injector is good. If those test pass, we do a leak test which pressurizes the injector while it is closed. You can visually see if the injector is leaking.
If any of the tests fail, we will ultrasonically clean and back flush the injectors. After cleaning we will re test, after which, a full detailed report is presented to the end user prior to the test and cleaning is completion.
On this customers job, the intake runner flaps is faulty. This is the cause of the excessive carbon build up. The faulty runner flap failure is directly related to the bad injectors being driven on for 30,000+ miles w/o repair. Also excess carbon build up issues on Cylinder No.4, No.5 & No.6 was caused directly from faulty injectors. If problem is addressed sooner (at 19,000 miles), these issues would be present today. Current milage is 64,902 miles.
