VT SS 5.0L cutting out at high rpm

[hsv8]

Hi guys,

I have a VT SS 5.0L which seems to have spark issues at high rpm (around 4000). It will cut in and out intermittently once the engine has warmed up a bit, making the car lunge back and forth (not fun!)

I have replaced the ignition module? (behind the headlight) as well as the coil and the plugs...

Any ideas?

My next guess was the leads, but it feels like ALL the plugs are missing, not just one or two, maybe it could be the lead from the coil to the dizzy?

Is there something I've missed, or has anyone else experienced this?

Cheers,

Kurt.

Change your dizzy cap??

Can that be done without taking off the intake manifold?

It can be done its just fiddly. Dont forget the lead order for when you put it back on! Took me about 30 minutes to do on my vt for the first time
