Slappii Posted September 10, 2018 Report Share Posted September 10, 2018 (edited) Hi so basic story. I tried to fit a cone filter I did it and then I forgot about the MAS sensor so I put the oringinal air filter back on plugged everything in and installed it as it was before I took it apart. Now when I start the car it stays above 1k revs and then starts revving by its self. Anyone had that happen ? Thanks in advance for any help !
