I've got a vx wagon, after changing the spark plugs, it started stuttering while driving. Thought it was the trans, bought another trans, changed it but the stuttering is still there. Temp gets to about half, and it stutterrs around 60km, more so when its in the first drive (overdrive). Tested some of the leads, one was a bit faulty,changed it, but it's still doing it!!! It's got me stuffed.
Any help would be greatly appriciated
Probably a faulty lead, you should have bought a new set, much cheaper than a transmission. If it is not the leads then it could be a faulty coil or fuel injector but when ever mine starts missing it's always been a faulty lead. The fact that the problem started after changing the spark plugs would tend to indicated that you might have damaged a lead when removing them or you cracked a spark plug.

I thought I was wrong once but I was mistaken.
Check Leads and plugs.
Check Coil Packs.
Check Connection to the Ignition control module another the coil packs.
It will an electrical fault, in the ignition system, not anywthing else.
Check your plugs, you might have cracked one putting them in, check leads are in right firing order. If not it's coil pack.
