grand prix mass air flow sensor problems

There are the 'normal and typical' symptoms that seem to apply to 'most' cars but there is also those that buck that all together and it takes a bit of diagnosis to isolate. So they can run with the MAF being faulty and plugged in, and my experience in dealing with this sort of issue is that each car seems to respond a bit differently. There were no real indications the MAF was dead, it never even set the SEL light, the only indication was the performance was definitely not what it should be. I swapped it out with mine and everything ran perfectly and as it should and the KR dropped to around 1 - 2* of KR. It measures the volume of air passing through the intake. No matter where the gas pedal was it registered the same air flow rate. The Mass AirFlow sensor is positioned in the air intake, directly before or after the air filter box. I monitored the MAF readings to see what his air flow was like and the values never changed, it registered only minimum air flow like it would around idle and once he was into the upper RPM range there would be several degrees of KR. However, performance was notably off, not really sluggish or anything but it didnt accelerate like it should have.

We made a few runs and everything ran perfectly.

Drove up there to help the guy out and took my scanner. I troubleshot a Grand Prix GTP in Kansas not long after joining the community.
