Believe MAF is Fried, Symptoms Sound Right?

[Swarzkopf1]

I have a 95 GT. The motor is stock with a cat-back exhaust and an adjustable fuel pressure regulator. The MAF is stock.

The car will drive normally sometimes; other times it feels like its running rich, and other times it spark knocks. Sometimes, it will literally change its demeanor during a drive; going from bogging to spark knocking and back to bogging, ect.

When the car is bogging or knocking, its registering a check engine light.

I've found that when I disconnect the MAF, the car stops varying between rich and lean and runs fairly well, much better. This leads me to believe that the MAF is the culprit- though I've heard that 94-95 GTs are prone to spark knock.

I've got a Pro-M 75mm on order right now, and am hoping that this cures the problem.

Any input? Do these symptoms sound right for a malfunctioning MAF? Thanks in advance.
