Everything fine,i was driving the truck for a pick-up and back to my yard,i left the engine to idle for 3 minutes and start shaking the engine and worst then befor to replace the 3th injector. Did again the leak test and i got bubbles again but now i didn't bar it to find out exactly witch one is leaking.when i did the first time leak test it was leaking only between A and B.thank you in advance

Sorry to hear man, one of the experienced gents on here will chime in to help I just looked at the page quick to see the sequence quickly but out of curiosity does the shacking go away when it warms up?
