Thanks for the reply. I forgot to mention that I recently replaced the plugwires and injectors while trying to track down a rough idle issue. When the car is working it runs very well. Intermittent problems suck.

The new syptom is a complete lack of power followed by a sudden "healing" where it returns to normal. It will them be fine for a part of a day or so only to run very poorly again usually after a hot start up.
