Not sure what you mean by "low tension switches". 12V supply is via the ignition switch and ground is via the ECU. Maybe you need to get a code reader on it if it's a MK2 (see Guides section for cheap [£10] ecu reader if you have a laptop). Sensors for things like water temp, air temp, air pressure and crank position can all give strange symptoms at times.

Give throttle body a good clean out with carb cleaner spray and all will be good again
