      hello all, i was once told that if you remove the connection to the
      throttle position sensor, the idle should rise. well mine doesn't and
      i still have a rough idle and blackish/blue smoke out the exhaust.
      also i just noticed that there is an air leak at the base of two
      injectors, could this be the problem with the smoke and idle??? i
      have a 1984 533i, i would appreciate all your help and support!!!!
