AOS cannot foul the MAF Boxsterra - Friday, 20 January, 2012, at 11:22:18 pm |
While it is unlikely some oil vapor can travel upstream. I wiped down the intake piping upstream... MarcW - Monday, 23 January, 2012, at 3:47:37 pm |
The oil certainly doesn't travel upstream while the car is running Boxsterra - Tuesday, 24 January, 2012, at 10:58:55 pm |
While the oil vapor from a failing AOS can't flow backwards while the engine is running... MarcW - Wednesday, 25 January, 2012, at 1:55:24 pm |

and since the business end of the MAF is suspended in the top of the intake pipe, the only way oil coming from downstream could possibly get on the MAF is if the entire intake pipe filled with oil. That is pretty much impossible. So perhaps oil got into your intake from the outside but it did not come from the AOS.
How does the vapor get past the closed throttle? I hear it's airtight. Boxsterra - Wednesday, 25 January, 2012, at 9:32:00 pm |
The throttle valve does not fully close nor does it fully open. There is a vacuum/low pressure... MarcW - Thursday, 26 January, 2012, at 6:17:13 pm |

Also, when you shut off the engine there is a vacuum in the system, not positive pressure.
You can get oil to the MAF ... Pedro (Odessa, FL) - Friday, 27 January, 2012, at 9:57:57 am |
Unless the CEL is on and the error codes point to the cats, not likely. I like the idea MarcW - Thursday, 19 January, 2012, at 6:43:20 pm |

I replaced my AOS about six months ago everything went well but after and more so now i have experienced a loss of power mainly around 4k to 6k rpm. I think it might be the cats..???
any ideas? this is a very frustrating problem for me. I cleaned the throttle body and ran some techron through the gas but it has made little difference I also replaced a MAF sensor but only as a result of my ignorance about AOS failures. the power will come and go sometimes
please help

If you already replaced the MAF, don't touch it again Boxsterra - Friday, 20 January, 2012, at 11:26:24 pm |
