Low revs on Vauxhall Vectra - what's the cause?
The revs on my Vauxhall Vectra CDTI have started dropping to 500rpm and causing the engine to struggle. It only happens every now and again, with the engine righting itself after a few moments. Any ideas?

Far better than previous Vectra. Now with decent handling and an excellent ride. Plenty of safety kit. Roomy in the front. Big boot. Good looks.
