Technical Ducato 2010 2.3 120 no power

[Buzzpotts]

Hi
My Ducato has 195000 miles on clock, when engine cold always starts ok and usually ticks over ok but occasionally runs unevenly and puts out a bit of blue smoke but won`t rev when throttle pressed, leave it ticking over 15 mins and it has enough revs and power to drive, after 5 to 10 miles vehicle runs ok.
Scan said air flow control faulty, fit new one, ran ok for 2 days then fault recurred, had throttle control body fit, again ran for 2 days then recurred again.
So far far spent over £600..... Can anybody help please !!!!!!!!!!!!!!!! ?

Sounds like a stuck throttle valve. Is there any evidence that a new one was installed, other than a 600 pounds bill? I once paid a similar amount for a new fuel pump and asked for the old one.
They gave me a large carton, but back home I found just an empty fuel pump/filter housing.

There can also be a wiring or ECU issue. The valve is opened briefly by the ECU to make the engine stop faster, a spring should close it. To find out, you need to pull the electrical plug on the throttle housing but it is very difficult to reach.

Many thanks for info, hoping to check it out over weekend, will let you know if I get a result

Hi buzzpotts I had the same prob as you and spent a fortune fitting new parts until I sent the ecu away to the ecu doctor in Plymouth and they found a fault in it and repaired it sent back to me and now my motorhome runs great so it might be worth you giving them a call on 01752346437

Hi John, at last I think its sorted.
£160 for Terraclean, clears all carbon deposits out of inlet manifold, back of valves, egr, cat and exhaust.
£193 for vacuum pump (fiat price, robbing bxxxxxxs) and that was fitted free by my little garage.
Everything seems to be working well now.
Regards
Howard
