That's why we recommend checking the check valve (about $15) first.  But, at 
the end of the day, the injectors are one of the most _likely_ causes.  Just 
unfortunately the most expensive.

And as a comment to a half-forgotten thread - you can't test Viton-tipped 
injectors with air.  In fact, the factory manual specifically states that you 
can't perform _ANY_ meaningful tests after they've been out of the car for more 
than an hour.
