Will a vacuum leak on the AOS affect the right bank more?

[chris97boxster]

I did try and clean my maf. ....the codes came back
so I bought a new one from pelican
code went away. ..but then came back again after 200 miles
Sometimes would show only 1128...clear it
then other times both would show up 1126/28
this all happened within a month
then I got 0102 & 1126/28
but I just replaced the maf? ??
now looking @ other possibilities like AOS
I will change O2 sensors if I have to
but just checking other routes 1st

@dale k.....try AOS 1st and c what results u get
maybe what I've stated might help in ur diagnosis

Ok. ...other forum ppl mention that the AOS
when it starts to fail, has oil on top of intake
where the hose goes.

Another mentioned about taking the oil cap off at idle
still trying to find that thread on here
Something about if it runs rough with out cap means
one thing...have to find it again

Others have mentioned to take the AOS line off the intake
and vent it into a catch bottle as they do in race track application

Things I will try when I get a chance
then decide whether to replace AOS

Of course if this does't fix the 1126/28 cell
then I'll b looking for some more input from forum members
