i agree with your assessment if this car did not have a mass airflow sensor attached to the air filter assy.

The mass airflow sensor has a sampling tube, which is measuring air speed, not air volume.

Am I missing something here or would decreasing the diameter of the tube increase the rate at which the air is travelling thru the maf sensor?

And wouldn't that increased air speed through the MAF sensor translate into it sending a signal for more fuel and ignition advance?
