    The car has a reall rough idle also. I found an exhuast leak at the muffler and the mid pipe. I have Cobb TBE This that could throw those cels. I'm going to check the ground strap

    well I a new gasket on the mid pipe to the muffler and pullled the intercooler of and re did all the hoses. I think the main hoses from the turbo was not on all the way. Now I reset the esu and the cels havent come back.
