Hi,
I have a Ford Transit Connect 1.5 tdci from 2017.
The timing belt had snapped, and we changed the exhaust and intake valves.
Now the car starts fine and iddels fine, but when you drive about 100 meter, we get a fault code P2279 intake air system leak.
We cant really find the leak. At iddle 800rpm the maf sensor measures 8,5 grams pr second, and it should be around 10,5 grams pr second.
Will a leak in the valves cause this fault code? Any ideas what i should look after?
Thanks in advance!
