Ok have had this since owning the car. I have tested the injectors and the tolerance should be -2.8 to +2.8. Mine vary between -0.20 to +2.0. So not the injectors.
I have also cleaned the inlet manifold and removed the egr valve.
No fault codes. Any ideas?
Someone said flywheel?? But that was done about 3-4yrs ago (about 30k).
