Hi,
My Vectra has developed a couple of problems recently,firstly when starting from cold on cooler/damp mornings my ignition light will stay on for a few minutes and the speedo and other gauges will come on and off intermitently.After five minutes the problem clears.The second problem is after the car has run for 10 k's or so if you stop briefly at a servo etc when you restart the engine will cut out when the revs drop when you slow down at a junction.It will only do it once then everything seems fine.Any ideas to put me in the right direction would be appreciated. Thanks.
