GS400 Mass Air Flow and Rich code
My stock MAF went out and I was forced to buy an autozone MAF from Duralast. The car starts up and runs fine but when I get on the gas hard, it hesitates and goes a second later. I am looking at the fuel trims and when I step on the gas the LTFTs go to about -30. So I am looking for a stock denso maf if anyone has one and some advice as to what maybe wrong. Also, before the maf went bad the car threw a P0172 code which is a system rich code. Thanks.
