My 1992 740 Wagon (192K miles) has lost engine power. It is not an intermittent problem or a problem where the engine hesitates. My wife drove it to the store and it was fine, but when she started it up to come home it just had less power. It takes a couple of minutes to accelerate to its top speed of 50 mph. I checked the air filter and related hoses, etc. for blockage nad cracks, but found nothing amiss. Any ideas what else to check?

Thanks for your help,


Andy
