Problem starting, Loss of Power

1998 BMW 740il Loss Of Power

My car started to loose power at high speeds a few months back. If over 85-95 mph on the highway, car felt like if would gear down and check engine light would blink. It progressed to the point that now the car starts after a few attempts, engine sounds fine, exhaust sound odd with a clear fuel smell, it runs but shakes with no get up, can't even get on the highway anymore. Im thinking its my fuel system... any feedback would be greatly appreciated thanks!

The flashing or "blinking" service engine light is indicating an over fueling condition that may damage the catalytic converter. There is a good possibility you have a defective or stuck injector, possibly ignition issue.
Take you car to Auto Zone and ask to have the codes read, they will do this for you at no charge, write the codes down and reply back.
Let me know.

Loosing power at sped


Where do you live that it is legal to drive 120 mph? Your hitting the built in speed limiter. The car is telling you to slow down.

1998 bmw 740il will not start even with new a battery


If you checked all the fuses try putting the car in neutral sometimes the shifter gets misadjusted and wont start till the car is completely in park.If not check for a lose wire to the starter.If the car has an after market alarm you will have to turn it off before starting there should be a little buuton under the drivers dash or kick panel.GOOD LUCK
