Review on Delphi AF10111 Mass Flow Sensor by Steve Brethorst

I ordered this for my 1992 Ford Ranger 4.0 V6. First the engine sneezed and died at 3000 rpm. I noticed a serious problem with my mpg (about half my mpg). I've traced the problem with another new set of spark plugs and wires, every type of injector cleaner on the market and a throttle body cleaner. After a few months I was still having the same issues so I reinstalled the factory MAF. He still lets me check the engine but it runs perfectly and the liters per gallon are back up to where they were before. I don't know if I was misled into trusting Revain to fit or if it was a defective product but either way I'll have to eat it as the box says 'No returns once it's there opened". I'm giving this two stars instead of one because it was my fault for not reviewing and researching this product more thoroughly.
