DRich,

Thanks for the reply.
When accelerating, it doesn't really surge per se, it just seems to take a long time to decide what mixture it wants/needs, and then hauls butt.
The ignition module is only 2 years old, as is at least 1 coil (don't remember if both were replaced).
The majority of the trouble is when the car is cold - once it is warm, there is just a minor hesitation most of the time.

It idles fine hot or cold. It is more difficult to start cold - longer cranking time - like I wrote in an earlier post, if it had a carb, I'd say the accelerator pump was shot. *sigh*
