I’m running ******* down ***** e85 mixture I see smoke puff out every now and then is this normal it seems to only happen when I run a e85 mixture or do I need to dig deeper I have a warranty but I would have to put my cats back on then take it to the dealership the car runs just fine other than the horrific smell
