2012 volvo vibration

UPDATE

After replacing injectors truck was ok for some time,but it felt like there is little bit vibration when accelerating.
Eventualy vibration came back.
It became more noticeable when weather got colder.
Even then,on sime trips truck was ok and on some it was shaking like crazy.
On my way to CA while going uphill,check light came on saying check fuel filter.
Filter looked ok.
In the meantime truck developed new problem,it would be cranking for 10-15 seconds before it starts.
Took it to the shop,they replaced fuel pump. Nothing changed.
Then check engine light came on,and code was something about boost. Shop replaced boost sensor. Light went off but shaking wasnt fixed.
Then i called my old mechanic,explained what was going on and took the truck to him.
He called me last night,i went to pick up the truck,then i got load heading to Memphis.
Truck is starting ok now and pulls better and vibration is gone for now.
What he did,he changed fuel filter housing,and he thinks that was the problem from the begining.
I hope this solved the problem. That vibration and loss of power was driving me crazy.

 

One on the left side of the engine.
Still have the same problem,it takes long time to start but doesn't shakes as bad as before.
Will go to dealer in few weeks to check cups ans injectors while they're under warranty.

 

Well,took it to the dealer,ran on dyno,had stumble on 75% load,fuel pressure was 60psi,boost was 30psi. They found cup#5 was leaking.
They replaced injecors 10 months ago under the warranty,but they said there is no warranty on warranty,so boss had to pay 5500$ for new injectors and cups. Starts and drives fine for now,knock wood.

 

Everything was done at Volvo dealer,so i think they were OEM,not sure tough.
When they replaced them first time,they said its new updated version of injectors,they're stainless. Now,they put even newer version,not sure what kind are those,but now we have 1 year or 100k miles warranty.
Shake in my case was intermittent also,it was more noticeable when climbing hills or when accelerating against head wind.
Even if i was light,i couldn't climb hills like i should do,it felt like truck was operating with 60-70% of power.
And fuel mileage sucked.
