Changed my ccv valve last week at the suggestion of my bmw dealer... Still no fix for my p1093 code... I did smell a slight rotten egg smell a couple times on the hwy last week... Wonder if this could be the rear cat that wasn't replaced like the front? I haven't replaced the fuel injectors or tested them other than my stethoscope test... dealer says they would need a few hours or more to figure all of this out... Gas mileage combined is 18... Also, I get a p3013 misfire code with low fuel and or when it's super cold 10 degrees... Not every time but has happens a few times...

Trying to think logically here and let all of these symptoms point me in the right direction...

Any ideas? Have a look at my previous list of things I've fixed... In other news I've got a coolant leak at the coolant temp sensor... Radiator was replaced 25k miles ago... I assume the hoses too?!
