2009 volvo D13 Jerking

When is the last time u had the filters cleaned and the next thing does it start ok or is it cranking to long this usually happens from cups or from dpf getting loaded with soot and it won't get rid of exhaust and start choking truck

 

Bring it to the dealer and have them dump the ECM or do a test drive with the computer on it.

 

Have a shop see if you have alot bubbles in the fuel return line. Might eliminate cups or will indicate that cups are in your future.

 

fuel lines are old...The rubber ones..

 

Hi George, I have the same problem on my 09 with D13 talked to a friend with many Volvo trucks he says he has replaced 8 to 10 bull gears or idler gear, when I explained how its running (one time smooth and has power, next time chugging and missing no power) he said just what his were doing and it was a worn bearing in bullgear throwing off timing . I am in the process of replacing mine.

 

just another note, have replaced injector cups , cleaned dpf , replaced turbo, new filters and problem remains. Not a fuel issue or sensor issue , tested injectors, egr valve, compression, turbo, my mechanic says if not show on the computer must be mechanical failure. I wil know later today when I pull the back timing cover. I tell u what I find. my mileage is 919500.
