Hi ford oc members Have a anoying issue to pick your knowlageable brains. 2011 fiesta 1.6tdci zetec just clocked 70000 miles. Today i drove car about 30 miles high speed limit. When getting into the 30mph i lugged engine 1500rpm normaly pulls fine but as i let off the throttle i got a constant vilant julting kangerooing. diped clutch pulled over tickover stuck at 1500 rpm no smoke. pull away all seems fine until loaded only ever seems to happen as i let off the throttle. No smoke anywhere no dpf to worry about coded out. Anyone had exsperience with this. Iv had it happen under high load since owning vehicle just got a little shudder when let off throttle then its fine. Had a maf sensor last month fuel filter cambelt ect trying to clean this issue up and it was due. Should have kept my old audi 😠

Just on my way home and engine management fault message. limp mode. Only 1 pending code turbo charger underboost usualy get that code at max revs. On live data whenever its idling at 1500 hunting the throttle possition shows 86.3% if i add 1 mm of throttle it drops to 20 odd percent idle drops to normal then picks up a lil. Also i can slowly press throttle and stays at 23 % even tho the revs are picking up then revs shoot up reading flys up to 86 % seems odd but its a cheap scan tool. I know its not the air doser as that comes up as relative throttle position. Have i self diognosed a throttle pedle sensor???? Anyone had same issue because i hate geussing at parts see video attached passenger takeing the video julting is foot completly off the throttle.

 

Self diognosed throttle body flap not opperting correctly unpluged car runs a charm now apart from rough engine shutdown and eml
