tried seafoam....good stuff

[greenskeeper]

So my 99 has 258k on the original injectors. Lately there has been an injector or two not firing smoothly (very evident when listening to the engine). Gave it a shot of archoil at the last oil change and that cleaned up the oil side. Tried seafoam for the fuel side....almost a full can in the fuel bowl, another can in the tank at less than a 1/4 tank. Started the engine and let it run for 1 minute on straight seafoam....shut it off and let it "hot soak" for about 20 minutes. Restarted and went for a hard drive for 10-15 minutes. Ran the 1/4 tank with seafoam as low as possible before refueling. All injectors are now smooth and quiet....try it before condemning your injectors and spending $$$$

Next go around, try the hot shots secret diesel extreme.
I typically run additives on a frequent basis. Especially a new to me vehicle.
