[QUOTE="doz_SR20, post: 553148, member: 9753"] I have now changed the turbo - the old unit despite being to my supprise healthy in terms of bearings etc had cracks around the wastegate and was therefore bleeding off exhaust when it should't have been. However the car is still as it was if a little better, and is still getting continually worse. I did a leak off test on the injectors yesterday and one was worse than the rest, so I was going to change this injector. However I did a diagnostics check tonight that revealed that my Inlet Air temp was reading -40! So I set about this evening trying to find the Air inlet temp sensor as they are only 11 quid from GSF. Problem is I can't find it for the life of me, I can find the inlet/turbo pressure sensor, un-plugged this and it confirmed what it was as the manifold pressure reading dropped to 0. I'm beggining to wonder if my car's got an inlet temp sensor at all as I really can't find it anywhere for the life of me. I've had the front grilles off, battery out etc with no joy. Any help appreciated! [/QUOTE]
