: Have you tried synchronizing the throttle motors:
: if not:
: 1) find a long deserted street.......road..etc
: 2) put it in first gear and leave it there
: 3) accelerate to over 5000 rpm
: 4) hold it at that speed for about 5 seconds
: 5) back down to a complete stop...still in 1st
: 6) immediately repeat the above... two more times for a total of three cycles.
: 7) at the end of the third cyclelet the engine idle at a complete stop for 5 minutes (BTW you can take it out of first...... LOL
: The TMs are now sync'd and should run better. I do this proceedure once a month. Also helps the gas milage
: i>: Can anyone pin point the problem of sudden rev drop when taking your foot of the throttle it only seems to do this when driving and not whilst stand still and reving the engine.It makes for difficult driving as when you let off it all seems to shut down ,not cut out but drop to around 12-1400 revs from say 2000+
: : Could it be the throtle motor?The BMW garage checked and in the fault memmory it showed faulty oxygen sensors.
: : Aidan
: : 850i '91----90k miles
How would this be done for a car with a stick shift (step 5)?
