    I have recently bought an e34 520i Auto in fairly good original condition. However, when I press the accelerator hard, it goes flat with engine almost cutting out before power sages up. I have checked the spark plugs and they burn beautifully. What can be the cause? Can some one advise me please.

    Thanks for the tip. I certainly will be checking it out today. I also think that I need to replace the fuel filter ASAP. Will keep you posted on any progress I make even though it may be small and tentative.
