Following on from the thread about "thrashing" the engine periodically I've got an intermittent problem that I think may be related. I'm not a "thrasher" but like to give the engine a workout every now and again. X250 07 Ducato 2.3 Multijet with 75000 miles.
But we've just done a lot of miles (I'm talking thousands here) in Scandinavia and frankly the roads are not up to giving the motor the 10 min workout proscribed. In fact I've rarely got it above 50mph and tend to stick around 2000 rpm in 6th. But every now and again, particularly if I've just used a high power setting to, say, climb a long hill, the engine suddenly starts misfiring and hiccupping (that's what it sounds like) under "normal" cruising loads. After a few minutes it settles down but the engine management warning light comes on (my ODB reader says Throttle Actuator Control Range / Performance Bank 1) and we go into limp mode. I've discovered that I can "clear" the misfiring by giving it full throttle for around 10 secs, but the light stays on until 5 restarts when it goes out. It seems to come out of limp mode after a 5 min stop.
My point - is there enough crap generated in the cleaning process that could cause this misfire? Or should I be looking for a dealer?
Interestingly, over the past 2 days I've been doing some higher speed motorway cruising and the fault hasn't re-appeared.
