Are the plugs in good shape? This might be a probable cause! |

You could reset the ICU... although that probably ain't it. |

you would not need to keep the revs up by foot under normal circumstances ,its all controlled by the ECU. sounds like an ECU related problem  |

wiring issue I would say or dodgy ICV
might be a blown ICV driver in the ECU but it would cause stalling when hot. |
