Anyone ever try a manual cleaning through the injector inlet or return lines?
I just fired the old lady up after setting many years. I put fresh fuel and filters on and purged the old fuel from the tank. When it first fired up I had all 5 cyinders going. Then she warmed up to 4.5 of 5 cylinders.

All 6 of mine were running without an issue or so I thought. Took them out at 110K and sent them for testing. One failed with bad spray pattern and lower pressure pop-off. cost me about $60 to test them all, fix that one and retest. Reinstalled and the wife even noticed that it was smoother.l
