The background to my problem is in the link. My gut is telling me that it's MAF related, but i'm no mechanic. My mechanic, on the other hand, feels it's probably not the MAF. Maybe it's just a coincidence that my problems started right after i cleaned/oiled my cone filter?

Anyways, the codes being thrown right now are:
P0300, P0303 and P0106

I understand the first 2 are misfires and the last is:
MAP sensor -G71-/BARO sensor -F96- implausible signal

My mechanic said it has something to do with overboost and boost regulation. My car is at just over 60K miles and i've been chipped since 40K. My car was sitting at the airport for about 5 days until sunday. Monday, i changed cleaned/oiled the cone filter and Tuesday i noticed the symptoms (sputtering at high RPMs and occasional blinking malfunction indicator light).

Things i plan on attempting myself:
clean the MAF by using isopropyl alcohol
clean/service my diverter valve

Any other ideas?
