Saab: running at a high rpm and doesnt seem to have the pick up it should, vacuum leak, logical investigation

Question

Answer
Todd:
 Can you describe the problem a little more? For example, with the engine idling, or with no accelerator pressure, does the engine immediately "jump" to the hi speed mode?

 Is there a check engine light showing?

  Consider the following:

 Throttle body defective, vacuum leak, bad electronic engine controller as possibilities...a logical investigation is required.

  Hope this helps,
