01 Busa dies intermittantly when rolling off gas

[redrideronbusa]

My'01 intermittantly dies when rolling off of the gas and the FI lights on. It doesn't miss, doesn't sputter,just immediately dies. It will never restart until i turn the ignition off and turn it back on. It Idles perfect but just dies when rolling off the gas. I seems to be a electrical problem. Any ideas before I have just start replacing parts. Everything stock except for the exhaust.

What he said. On the 99 it is right next ot the ECU, under the main seat. It is a white plug on the kickstand side, with four holes and two pins. Use a wire to complete the circuit, and a code should pop up where the clock is on your dash.

Once you have that, bring it back and perhaps the .org can help you out more.

Good luck.

OK-The tip over switch was the culprit. Replaced with a new one and problem solved.
