hi there just wondered if anybody else has/had this problem i have a faboa 1.4 16v and on long journeys i get a sudden loss of revs no matter what speed i am doing its as if its about to cut out but then just carries on as normal for the rest of the journey, it does it for maybe a second but is very noticeable and a little worrying. also before i start engine my exhaust management light and epc light flickers as if the bulbs are loose is it common for these to come loose? all the other warning lights are fine and they all do go off once the engine is started. thanks in advance for any help.

The lights are LEDS not bulbs, so it sounds like you have either a faulty connection on the instrument cluster, or bad wiring between the ECU and instrument cluster. This would also explain the cutting out. Code scan may tell you more.
