Re: dealership fuel injector cleaning
I have ran injector cleaner through the tank a couple of times and have not seen any change. I am having a hard start problem both hot and cold and the engine is running rich. I have checked or replaced everything. The O2 sensor, fuel pump is less than a year old, checked all of the ignition system, timing, ect ect. The only thing that I can think of is that I may have a leaky poppet valve and cleaning the injectors might help.
