Could it be the plug leads--how old are they?

Can you avoid it by using light throttle?

As in is there a certain amount of throttle over which it gets crap

Thats what my other car did when the plugs were flowered :mrgreen:

Well, it should not have much torque under about 3k, but its the variation/stuttering of torque that suggests issues.

If it turns out not to be a fault, a supercharger should help!! :mrgreen: :P

what do u mean by original ones?

Original one that came with the car 5 years ago?

I would just change them + plugs, I felt a night and day difference with new ones in.

Happens from 30% throttle or higher.

I checked the leads and they seem to be the original ones.


That sounds EXACTLY like the issue i had with bad leads and plugs, get some good quality plugs and leads, even if it doesn't fix it, its still a good thing to replace :D
