99 Porsche boxster unstable idle! revs up constantly maf related?

I have a 99 porsche boxster, 5 speed manual, 48k miles. Its my daily driver and i need it fixed asap. It was running perfectly fine when i purchased it several months ago.

I bought it with full service records for mods/maintenance since about 18k miles so it was cared for. Other than an oil change and drive belt replaced, i didnt do much maintenance for the short period of time that i owned it.


When i started it up last monday afternoon, idle would stay at about 2500 than when car gets a little warmer it would just constantly bounced from 1200-2000 rpms like shown in the video below.

1999 Boxster Base Idle Problem - YouTube ( Not my car but does the same excact thing )

Engine check light also came on, Here are the codes:

P0102 - Maf low input
P1123 - fuel and air metering
P1125 - fuel and air metering

What could it be? I cleaned my maf with maf cleaner from a local auto zone and still no fix. Should i go ahead and purchase a new one?

If someone experienced a same or similar problem please help me out! still nube to pelican parts as this is my first porsche so help me out!
