Hi this really is all that is stopping me enjoying my Lexus conversion now. It always needs a bit of throttle to start, wont just start on the button. sometimes it will idle ok, if I rev it and let the accelerator pedal return it usually cuts out. Then is often hard to restart, will start if I keep the throttle wide open. Pain in the A*SE when coming up to a junction if I don't keep a bit of throttle on it cuts out, but next time it might idle ok. It pulls like a train no misfires or hesitance just the idle problem, I have no fault codes. I've set the TPS, cleaned the IACV (though i'm not convinced it is working, is there a way of testing it? New O2 sensors, new temp sensor, crankcase sensor, cambelt etc.. all new condensers in the ECU. Any one point me in the right direction where I can look to sort. Cheers.
