a couple of things...
the error code doodah won't bring up an error code unless it's getting absolutely no signal from what it's looking for. If it's not completely stuffed, the computer reports it as fine.
Secondly, your car doesn't have the wire thing that you hear so much about. The MAF sensor works differently in CA20 engines... Take the air cleaner off, and reach inside the box, and there's a flap covering the bottom part of the air pipe. That's your MAF in the CA20. computer measures how far the flap is pushed back.
