I'm not sure how many different ways you can ask about a rough idle, for example, but I think we're going to find out.  Should we do anything for truly generic open ended questions that have no angle for a specific make/model?  

Should we merge them?  If so, how?  All into one, or maybe let there be one per engine configuration (I4, V6, V8, ...) or manufacturer (GM F-Body, Ford CD3, ...)
