Engine Performance problem
1985 BMW 518 4 cyl Two Wheel Drive Manual 160000 miles
Have had this problem for a number of years and it has progessively got worse. After 2-3 hours of continuious highway driving (100-130kph) the car would surge and then backfire and will not respond unless accelerator is down to the floor or nothing on it at all. It's almost as if there is a fuel blockage or shortage. Stopping for an hour or so and I can drive for another 40-60 minutes before the problem occurs again. Towing a horsetrailer or caravan and the problem occurs after an hour or so. Happens winter or summer. Under normal city driving there seems to be no problem.
