    Got a intermittent type of misfire on my v70 2.4 diesel 2005. Does it more so when engine hot or idleing in traffic, starts to kick or idle uneven. Sometimes does it at 47 to 50 mile an hour at 16 to 20 RPM. Above 50mph and over 20 thousand RPM runs fine. No error codes on my maxcom or Volvo Dice unit. Runs fine from cold to warming.

     Check the Fuel Quality? Water or urine in the tank, If it's Got Political bumper stickers on back , there's a greater chance of that happening too.

    Quite recent, changed it thinking that could of been the problem. Only starts to do it on
    a good run, gets more prominent need hard acceleration. Going to do a chemical test
    when kit comes see if its a gasket or cracked head but no signs of that ln the oil or
    water or bubbles in the expansion tank.
