Hi guys.

I was changing oil today and while looking through the MAF found that the ETA opening is dirty with black junk, so I removed the MAF and cleaned the ETA.

I did clean it a month ago and now it's dirty again.

What does this mean, ETA getting dirty and fast?

Also while looking through the ETA to the inside of the intake manifold there seems to be some gasoline smell.

Could this be from the MAF giving false reading?

Car is : 300sel with 246000 km
