Got an 07 l200 which normally runs fine but once in a while it plays up by dropping power around 2000rpm or between 50-60 mph. Doesn't do it all the time maybe a couple of days then clears it's self. Almost feels like fuel starvation as not a misfire. Ideas?

what 2007?

07 elegance automatic

Doh! Diesel

ha ha try the SCV

or I am told there is a small bore pipe that can block too

U need to join the forum then u can see all the site plenty of info on both these with pics and fixes

some early autos have gearbox loom issues too which can affect it

always worth changing the fuel filter though even if it's recently been changed
