Hi guys I'm hoping you can shed some light on the fault code for me, I have a 2014 Skoda fabia se 1.2 htp 12v CGPA and it keeps throwing up a eml and fault code is p0172 and the odd map/maf throttle correlation code and I have tried everything in my power to resolve them by doing the follow I know it's a expensive way to try and resolve things but I was pulling my hair out

 

Replacing

coolant temp sensor 

Crank sensor 

Cam sensor 

Before cat 02 sensor 

General service on engine 

Timing chain

Map sensor with Lucas one 

 

I am now at a dead end with it on what it could be shotting the eml on I am gonna test pcv valve when I have time to see if that is letting in air but does anyone else have any suggestions, it runs lumpy on idle 

Has a compression test been done at any point?

No my friend
