I have learned a great deal from watching Eric O of SMA, kind of funny I'm currently watching a video of him troubleshooting an ABS issue and making an educated guess. If you ask me it's right in sync with the issue at hand that we are having with our R50's. So Unfortunately I was not able to clean my OEM MAF Sensor because I was not able to locate any MAF cleaner at the local parts stores(they were all sold out for some strange reason). I guess you can say that my OEM MAF Sensor was no longer serviceable due to a rusty and stripped-out screw, so I would not have been able to remove it from the housing to thoroughly clean it anyway so I just replaced it with the new sensor and housing I ordered. From what I could see through the mesh on the front of the old MAF housing the filament was indeed dirty, so long story short it seems to have fixed my stumbling idle issues, and my R50 idles smooth again. The replacement MAF now reads closer to 3.5 g/s once the engine has reached operating temp vs the previous 2.97 g/s with the old MAF Sensor, I would also like to mention that I now have better acceleration too, and the fuel trims are slowly working their way back down. So If you tried cleaning your MAF and that didn't correct the issue just replace it. Here's a picture of my OEM MAF Sensor and housing.
