Occasional Jerk Both Cruising And On Boost R33

[bombastic]

Hey guys

Since I got my R33 I haven't worried about this as it only happens very occasionally, maybe once a month. It feels as if I just put my foot on the brake for a fraction of a second, then it keeps going as normal.

It can happen while I'm cruising in 5th (not accelerating), or accelerating hard in 2nd, etc. It happens at low RPM's, around 2000 say.

I changed the plugs when I bought the car, gapped to 0.8 iirc.

Any ideas what it could be? I want to do a track day so I'm keen to fix it.

Thanks!

Got that same problem when cruising at 180km on the highway on 5th gear. Ocassional jerk. My coilpack needs replacement as it's really worn out. That was my problem. You'rs could be different.

Don't spose it's a simple task to check if that's the case?
