Hello folks
Just failed MOT, running very rich. Have PPE manifold, some high flow CAT, AEM intake and filter. Please advise what might be causing this. I have Torque app, no codes but it was defaulting to open loop this morning and said system failure but no engine light etc.
Thanks
I've been told maf does not throw a code of faulty ?
What did you get emissions wise?
