HI I DRIVE A VAUXHALL ASTRA TURBO DIESEL WHEN I COME TO A HILL OR PULLING AWAY ENGINE LOSES POWER AND BLACK SMOKE COMES PUMPING OUT OF EXAUST PIPE ON LEVEL ROAD ITS OK WHAT IS THE PROBLEM
sounds like fault is on air intake system ,is air filter ok, is there any blockage to intake hoses, are turbo hoses ok and not collapsing when under full demand [i.e. when accelerating hard up-hill!
