I've got an 03 Sprinter 311, 2.2l that is currently my home in the UK/EU.
Starts fine, no smoke, idles great, but then if you rev to about 1500 and then let it idle, it kind of hesitates a little, then idles REALLY rough (reminds me of my old Subaru when it would clog a spark plug).
It has a brand new air filter and pulls/revs pretty much as usual after 1500. The thing that has me stumped for diagnosis is that it's only sometimes a problem. Drove 2 hours yesterday and it was fine one intersection, shakes off the line at the next. Doesn't like parking/low speed stuff when it's being shakey, like a power loss.
It's getting a new clutch soon (slips if I punch it in 4th or 5th, and engages quick at the point where the pedal is almost all the way out, so I think it's worn right down?). It also copped a few litres of diesel on the front/engine bay when the fuel hose that goes to the rail/under intake housing popped off from a dodgy plastic clip.
So far I can think of worn clutch/flywheel (but it's not all the time e.g. On some fresh starts), injectors (which I can't afford to replace), busted crankcase vent to inlet port hose (anyone know where this f*cker is? Haynes says check the hose but stuffed if they have a pic/drawing for me), sticky turbo vanes/egr (but zero problems in higher rpm).
I'm stumped. Anything I can try/look at before I spend half my holiday budget at the local van mech? Where the fck is that second breather hose at? Am I going to fck it completely if I keep driving it?
