So I just changed the fuel pump, took out thefuel pressure regulator and added an adjustable one instead, and the guage on it doesnt work so I dont think its adjusted properly.. I also put in a newer IACV valve. Now the car is running horrible, and will backfire after running for a while when im slowing down.
Could it be the adjfuel pressure regulator is garbage and I shoulda never have never installed it.. Any thoughts would be ausome!
