  • a31 cefiro rb20e idle issues

    hey guys I have a rb20e cefiro I have recently put a new engine in to it as my old one had no compression.
    after replacing the engine my car now idles at around 2000-2500 rpm at all times and has no power under 3500 rpm
    I have changed the
    ecu
    afm
    tps
    I have also cleaned the
    aac valve

    I have tried to check the tps for the correct voltage but have had no results
    does anyone know whats wrong with it I am over it and about to smash with a hammer

    Have you looked for Vacuum leaks. on FI engines, vacuum leaks cause higher idle speeds.
