I hear a vacuuming noise coming from the boxster
 

I heard this the other day but thought some one was vacuuming there car in the next garage. Well I went out for a new bulb today and left the car running after I pulled into the garage and vrrrmmmmmm there it was coming from the front passenger side.

There is no code showing up at the moment so any idea's whats going on? I should mention that the car is running lean and I smell a rich mixture of gass from the exhaust. Ontop of that I had a error code that cleared relating to the evap emission sensor.

Radiator fan?

Yes, radiator fan. Or fans.

Is it normal?

How can your car be running lean and rich?

You need to get yer ear to the source and report back.

I dont know how to word it but I smell a really strong gas smell and the car is not running as fast as normal.

I am going out to try the turtle wax black box right now and I will investigate the vacuum noise.

Hopefully the wax will fix the problem. :D
