Is the car making boost? What is the vacuum pressure at idle? Does it run really rich when hesitating?

As you can see by the wide and varied amount of answers without you being a little more specific its a hard question to answer.

The GTSt has a tendency to miss just as peak boost comes in at about 4-5000rpm especially at full throttle. In can be a problem associated with the high KV (firing voltage) at this point.

There is a number of reasons and a number of cures for this fault, the more info you provide the closer we can get to an answer.

last i heard from Marv is he was going to throw some new plugs at it to start with. I found out some more of how it happened too, it would seem he had been giving it some stick when it just went flat and started spluttering. I just havent seen him online since
