I had something similar, but the car never ran quite right. I pulled out the JB4 and then reinstalled it and never had the problem again.
Maybe I had a loose wire or bad connection somewhere. |

I have had this problem when I reset my adaptions and did not reset the ECU last. It can be fixed by resetting the ECU, not just turning the ignition off.

I may be a fool...
The same thing has just happened to my car after adaptation reset...
 Not sure how to reset ECU so I had to pull the battery cable for 5 minutes, then performed a throttle switch reset.  This seems to work for me to restore normalcy. Hopefully this information is helpful for somebody who panicking as much as I was.  |

This happens often during resets. You will thorugh Trans codes, use BT to clear. If you do throttle valve adaptions, the car will hicc-up with throttle angles unless its done correctly. There is a thread on how to do it properly in this fourm.
