hey guys i got an 05 di-tech factory. unfortunatly ive been having dramas with it(the eng seized a few months ago). its seems to have a tempremental lack of power. i can´t associate anything with it. some days on the flat, full throttle it will sit on 85-6 but normally it only sits on 74-5 is this normal? also i was wandering if any 1 had the diagonstic fault code identifications. i have a few common faults stored in my memory but i don´t know what they are! help!
