Hey all
I have a 96 VS commodore running the ecotec v6 the car has done about 140,000kms. all of a sudden it has started to run really rough as if it was only running on 5 cyclinders, have done a compression check and is all good, also change leads and plugs, have also had our snap on scan tool on it but it is coming back with no faults, no engine light or warning lights are comming up while driving. It doesnt seem to be missing on just one cyclinder
Any help would be great.
Thanks
Daniel

The coil packs are noted for occasional failure / breakdown. Try a known good coil pack, and see if the situation improves (rather than buying one and finding it is something different).

My suggestion would be o2 sensor, try swapping with another vehicle to see if problem is transferred to other vehicle

Sounds silly but check your sparkplug leads. I had a VS ute which suddenly started running rough. Turned out someone had used VT leads on it, which have a different length and a kink near the cap. One of the leads had shifted slightly and was touching the

I used to own a 94 VR exec that had a very similar problem, turned out to be some crap in the fuel filter, give it a good bash or better yet change it and see if that improves the problem. Hope you find what it is mate.
