Re: Can you Clean Injector Spool Valves?
I don,t think you fully understand the purpose of that TSB. Its not that your injector spool valves are dirty or gummed up. They are essentially broken in. Just as the engine itself gets broken in over time and mileage. Because they are "broken in", it allows for a closer tolerance between the spool valve and bore causing increased striction. The cycling of the spool valves on shutdown is to shake the oil out of the valve to decrease striction. ( Grampy_Jim has tried to explain it at least a dozen times).

My 04 seems to be suffering from the same symtoms, although it doesn,t sound like its as bad as yours. I will eventually probably have to take it in and have the TSB performed. [img]/ubbthreads/images/graemlins/smile.gif[/img]
