Question 02 sensors & Trouble codes

I just became a new owner of a used Boxster S.

Thanks for the replies to my previous post.

The car seems pretty tight but I have a few codes that are set, apologize for my lack of experience with these flat 6 engines but I would like to try to sort them out myself if at all possible.

P0102-Mass air flow sensor, I have heard these can be cleaned before you buy new, What should I use?

P1126 and P1133 are both oxygen sensing adaptation, lower load banks 1 & 2

Since there are 4 O2 sensors, Which ones are these?
I cleared the faults, if they come back should I replace the o2 sensors? I don't think these can be reworked.

I can't beleive I made such a impulse purchase with such little research.

Can anyone give a sound judgement about this vehicle.

It only has 38000 miles but it has some issues which I have yet to deal with.

My questions:
1) What years are affected by this RMS leak or IMS bearing issue?
-All but 2010 (poss 2009-not sure)
2) Why are clutches and axle boots in need of replacing at such low miles on a lot of threads I have seen? When I purchased mine the previous owner said the clutch was recently done.
Clutch dependent on driver-Axle boots-6sp go quicker than 5
3) Is it normal for the idle to jump while finding it's true idle rpm? And if not what sensor or part is the cause?
I would start with a cleaning of the throttle body-should cure it!
4) With such a large capacity of oil capacity in the engine, is there any need to add oil within the 15k life of the oil?
I would never let the oil go to 15k....mine is 3-5k, but that's just me....I never have to add oil between
5) How reliable is this engine? Again there seem to be a lot of threads and issues which I don't expect from a Porsche.
dependent on driver (and luck-lol) some people have 150k to over 200k with no major issues.....just take care of it! and drive the piss out of it!
Thanks in advance for your responses
Seriously.....don't worry so much about it....take care of it and drive it!

+1 on previous post. I would just add... You hear way more of what has gone wrong with my boxster than what hasn't on these sites. Yes there are issues out there, but if you do proper preventative maintenance you can avoid most of these.

And yes drive the piss out of it. Unscientificly, people tend to have less problems with their boxsters if they drive it like they stole it. idea is the oil is heated up to proper temps and that was how it was suppose to be driven.

IMS issues are largely a non-issue for 2006 and later cars, and completely an impossible issue on a Series 2 car. Your car may have the dual row bearing, which is more robust than the later single row, but I'd still swap it for the upgraded piece if it were my car.
