    Can you give more details, year of the RX, what was the situation leading up to it, was it rebuilt recently, any fault codes?

    There are no fault codes, its a 2001, not sure about the lead up to it, it has just come to my shop, as i said i tested the air pressure, fuel, pressure, reset the throttle bodies, reset the TPS on buds, it will rev to the limiter, but when the throttle is released the craft just stalls, i haven't disassembled the fuel rail for inspection as yet, but its strange that it will rev cleanly just will not idle, any help would be great.

    Have checked air pressure, and when the craft is running i can't feel or hear any leaks.
    The idle is non adjustable on a DI motor, someone had tightened the throttle cable to make it idle, but this bought up a fault code, back the cable of, code went, but now will not idle.

    just for test purpose try with a vise grip to clamp the return fuel line on the fuel rail to hold pressure on the inyectors. I have done it to diagnose a bad fuel regulator since its asembled with the fuel pump.
