Hi ive been getting all kinds of different codes up and keep getting them fixed no the same 1s r comming back again.I was talking 2 a mechanic and he said swap the ecu over.I have a 2003 st170 he said just buy a 2004 st170 ecu and put it in mine he said it will get rid of my problems cause he said there must b a intermitant fault with the ecu i have.Has any 1 else heard of this problem or this fix?Arent st170s hard on lamba sensors and other stuff?
