need help 1990 750il low rpm hesitation

hi need help
the car has 88000 miles
own it for a year brought it to a local mechanic changed plags dist cup o2
sensors worked for 2 weeks on and off and still told me that it needs intake
manifold gaskets
well i think he is guessing
the car starts up no problem at low rpm the engine light comes on and hesitation starts. If you press the gas pedal lightly the car does not accelarate let the gas go a little car moves a litlle faster. if youstep onit wants to fly and engine light goes off
some times hit a bump and seems to pick up speed <not sure though>
turn the engine off and restarted fine for a few seconds
any suggestions?

Welcome to the Werkz.

The symptoms sound like they are related to the Air Flow Sensor, or possibly a vacuum leak somewhere.
