I have a 1990 740 turbo with over 200,000 miles on it and recently went through the same experience. Relucently I took it to the dealership and after a month of trial and error they thoujght it was the ecu, which turned out to be false. At the end they changed a fuel rail and it has been running fine since. Cost with tune up and labor and parts $900.
