my 1998 micra 1.0l has started doing this and i have no clue every few minutes it will drop out the revs and nearly stall and then the car opens the gas a little to stop it 16 secs in the vid the car is heating up fast aswell aboult half way the temp gauge and it does this within aboult 5mins and the fan does not kick in is this a bad temp sensor or something along those lines
