So after putting in a New AFM, my car starts up and runs fine until about 3000-4000 RPM which is approximately at 55mph. when it gets to that point, a huge HISSING sound is present. I dont know where it is coming from, i checked the IC pipes,and tighten them up and checked for any cracks. does anyone know how could i check specifically where it is leaking from? or should i just do another close inspection on my hoses? clamps? etc? any tips or tricks i could do to test where it's coming from?
