Hello guys!

Thanks for your help!

I got rid of the pre-cat and cat a while ago last summer 'cause (like you) I suspected that! The muffler is Ok to. The problem really comes from unbearned fuel, but I dont know how comes there is unbernead fuel at the exhaust... But I agree with the fact that doing a gaz analysist at the exhaust tip would probably confirm that fact. I'll check what I can do to have the gaz analysed. But like I said, after 1 year of diagnose I am 99% sure it is raw fuel.


Why raw fuel??
