Hi guys,
My van is a 2007 2.3 120 Ducato with 205,000 miles on the clock.
She used to run as sweet as a nut.
Last week I got the dreaded power dropping out whilst cruising down the motorway. Engine management light came on and sure enough it was the classic P0638 Throttle Actuator Control Range/Performance.
Purchased a new throttle body along with the new wiring harness and successfully fitted it.
Sure enough it fixed the error code.
However, it now idles in a very strange way in that it sounds like the engine is being starved of air then all of a sudden it gets the air back again.
I removed the intake pipe from the throttle body and sure enough the butterfly valve is closing then opening then closing then opening etc.
But sometimes it doesn't do it say after it's warmed it. Come back and start her up 10 mins later and it's back to doing this strange idle.
I've tried to figure out what it is but I'm at my wits end, plus I don't have the time at the moment to spend a good day or so looking at all the various bits.
So I figured I would ask here and see if anyone could point me in the right direction.
I've attached a few screenshots of various sensors so you can see what's going on.
I do have a YouTube video but I seems I don't have the privileges to post the link....
Any help or guidance would be greatly appreciated.
Cheers
Steve
