somebody please help me before i take a sledge hammer carÂÂÂ

right every now and again the turbo almost cuts out as if its in a safety mode or something iv just replaced the air sensor as thought that was the problem but it still does itÂÂÂ

its a AUM engine on a 2001 Y-Reg its done 70,000 miles its had its fault code read as the engine management light came on when the air sensor packed up but has no other codes comin up

any help would be excellentÂÂÂ
