I reciently bought a 1995 calibra turbo 4x4 which has covered only 54k. Some days the car drives a dream but others, it acts like there is no turbo on it! Boost is all over the place even though its reciently had a new actuator fitted. Car often smells strong of petrol and the engine man light occasionally pops up....... leaving no fault code though! Swine! Someone help!
