Faltering Frontera - Frontiersman
My 1997 Frontera Sport has done 160,000 miles, and, despite the brickbats often thrown at this breed, has been very reliable and mostly still runs sweetly. BUT, in recent months the (regularly serviced) engine has sometimes, and increasingly, started to cut out when cool (not cold) often several miles into a run, and usually when cruising steadily with the foot just eased off the accelerator. The engine can only be restarted by switching off the ignition completely first.

Several garages, Vauxhall and not, expensive and very expensive, have tried to diagnose and/or remedy the problem (nothing shows up on the diagnostic testing gismo) but never with any success. I'm reluctant to dispose of the brute, but it's getting dangerously unpredictable to drive. Any ideas? Has anyone else experienced something similar on a similar vehicle or engine?
