Lack of power, unable to rev beyond 3800RPM This seems to be a reoccurring problem with these cars but no one as posted a definitive fix? First we changed the MAF and went through the process of coding in on our Autodignos machine unfortunatley it doesnt tell you if the coding as acctualy been successfull! The rail pressure appears ok, the air mass and boost are down on desired values but I guess they would be due to lack of engine speed. We removed the cat which made no differance, replaced the map sensor, cleaned out the EGR and tested operation.Removed the inlet manifold and checked the swirl flap operation and security.Now running out of ideas?
