Maf cleaned
Okay so the car was very bad on my fuel going from 23mpg highway to 17mpg and 14 in the city... I took out my MAF and it was filthy... I used a cotton swab and alcohol ( be very careful so you do not break the thin sensors ) here are the pics..
p.s sorry camera phone is bad lol The little sensors are soooo shinny now..

okay just took it for a drive, and I can feel the difference, especially on idle, just sits at 850rpm and barely moves, now lets see if it helped the gas, i'm halfway between quarter and half and only have 60km on the tank :S

It appears that misinformation is being spread around lately and that resetting the NVRAM (20x brake stomp) is becoming as common as changing ignition coils for everything in the world.
Only way to clear the KAM (such as fuel trims) is by disconnecting the battery or pulling the room fuse as Team mentioned above.

p.s i told my wife I was called a noob and she made a sandwhich and burnt an 8 in to the top of my sandwhich

The 20x brake stomp clears the profile and allows the PCM to relearn it.
Its required when doing a motor or PCM swap, but also anything that deals with the e-shaft such as cleaning and/or removing the e-shaft sensor, removing the position plate, or the actual pulley.

The NVRAM is used to memorize the profile of the eccentric shaft positioning plate.

Reason why there is a separate area of the PCM for this is so when the KAM is cleared (disconnect battery or pull the room fuse), it doesn't clear the NVRAM.
The 20x brake stomp is the only way to clear the NVRAM.
