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?

The thing is when is cold doesn't shacking at all, runs very well,when it's warm start shaking
