Review on Walker Products 245 1045 Sensor Assembly by George Scoles

I bought this sensor for my 1998 f150 4.6L engine which had poverty codes. The item arrived well packaged and protected. This part looked just like the original. At first I was very impressed. I connected the sensor and started the car, everything seems fine. An obd2 reader said otherwise. Maf showed zero. When I stepped on the gas, the car turned off. Plugged the stock sensor back in and the truck was back where I was before. I had really high hopes for this sensor. Hope the seller sees this and fixes it.
