I love my 2002 ALfa Romeo 156 GTA, it was running fabulously until i overcooked the dif in the January Snows, since having a new Q Dif fitted i keep getting "Engine Management Failure, contact dealer", all attempts to locate the fault have failed. I Have changed all coils, timings, even had top end service to no evale. BUT would somebody please tell me why, if i run my air conditioning on full i dont have engine management failure. Obviously this is a quirk of Alfa Romeo electronics but i want to fix the problem. Any Ideas?
Thanks
Thanks
