nothing to do with yr compression..all points to the MAF..but the car has a IAFM...hmmm...no maf kah? Not very familiar with Campro yet...can you take off the air filter and see whats behind the or is there sensors around it?
also check the hose around the air filter box connecting to the air intake to the bottom of the box. There may be some leak thats confounding the readings(meaning theres more air than fuel entering yr engine)
Can the intake plenum to engine of the campro ever crack? Do some google on this topic bro as I havent had enough experience with the engine yet. But these are typical symptoms of issues seen with other cars.
