Sparkplugs??? fuel pump on its way out?? when you put your foot down does it fell like its trying to go but is being held back??

Also check the fuel filter as if it not been changed for a long time it may be having trouble pushing the fuel through.

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

 

[Moschops]

What about doing the ECU diagnostic check. That will rule out a few things.

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.

could be Maf or coils too.

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

One melted spark plug later and all is fine in the Marv garage

[marv]

yes one of sparkplug ends melted off

 

[Sarky_FCUK]

he is lucky the melted end of the sparc plug didnt stay in his engine.

The question is though .....wht did it burn the tip off the spark plug?

 

[tigger]

blimey, for once I was right on summat!

maybe the sparkplug rating wasnt right?

 

[RoboPope]

id put my money on too high a boost level and not enough injector capacity.

 

[Sarky_FCUK]

run lean, too much heat.. la la la , not enough petrol....

Detonation........ bye bye mr spark plug tip...........
