Review on Enhance Engine Performance with the Hitachi MAF0033 Mass Air Flow Sensor by Oscar Thompson

My daughter's check engine light came on. I hooked up an OBDII scanner and it showed a rich fuel mixture. I replaced my native DMRV with this one, reset the error, the light hasn't turned on since. The car now idles better and no longer stalls when stopped. I chose this one because the one I replaced was also made by Hitachi. Installation was very easy. A rich fuel mixture can mean several things. This is usually caused by a bad MAF so I changed it first. Luckily that was all I had to do.
