Hope someone can give me a hand here--been having some trouble with the check engine light after I had my STOCK exhaust system put back in my 1995 850 Turbo. I checked the codes on the A2 port and came up with 522 and 153. I reset them yesterday and today, again, after some wide open throttle on the highway, the check engine light came on again--same codes. I don't have a list of ECU error codes, does anyone know what these codes are referring to and what is the likely cause for these codes to be stored? Any possible solutions?
Thanks
