Works excellent! I had a fuel injector code, but my injector was good, and all of the wiring was good also. The only other thing that could set the code, was the ECM, it was supplying a voltage signal to the injector, for no reason, causing rough idle, and the engine code. Fixed the problem immediately! Thank you to Flagship One!Verified purchase: YesCondition: Pre-owned
