Hello guys

I am glad this website exists for all Buick owners

I like my little buick regal LS 2003, but I noticed few months ago I have the famous ODB code P0441, exhaust leak detected...

My gas cap seems fine and I also replaced the famous vent solenoid by a very new one, I cleared the error but within 1 day I have seen the error is back pending..so something isnt fixed yet

Any idea ?

Did anyone get through the same situation and maybe that was something else ?

I have noticed the air filter doesnt seem to fit properly, even though it is not exhaust, I was thinking perhaps the system will show up as P0441 even though it is not ?

Thank you for your advices
