I'm in the middle of diagnosing a starting issue, I pulled off my J hose to replace the Temp sensor and found this crud sitting inside the throttle body and slightly into the J hose. It wiped right away and wasn't anywhere else that I could see (I didnt open the throttle body) but I'm clueless as to what it is, any ideas? Whats a good cleaner, brake fluid?
I've only owned the car for a couple months so I don't know the maintenance history, it ran perfectly until a starting issue that is unrelated (I assume)
