2004 VZ SV6
So my 2004 vz commy has been playing up for a month or two now.

In any gear, if you put your foot down (not to the floor) the engine will start to stutter + shake like it’s about to drop its guts until you give it abit more gas and it’ll go back to normal.

Also without fail, once you get to around 80kms or 4th gear in active select and put your foot down slightly, the same thing will happen. Engine will stutter and shake like it’s skipping a gear or trying to get enough power not sure, but once you put your foot down more and get passed 80 it feels like the car loses power idk I’m not in the slightest way a car guy.

All suggestions will help and much appreciated!

Had a similar thing with my VZ a few years ago. One of the coils was bad. Idled fine and drove normal until it got to 80, then it would start to hesitate.

Coils are a common problem with the VZ. Heaps of threads with coil problems.
