Noticed it when I bought my project but thought it must have been bad fuel as the car had sat for a year before me purchasing.

When I picked it up it ran fine but now it has started to miss again.

It only does it down low in the rev range while accelerating, once you get to about 3000 or 3500 it does away but then the auto shifts and off you go again.

Ive checked plugs (seem fine), air filter clean, leads look good.

Im not to fussed about it but if its something easy ill fix it before swapping the v8 from my donor in as teh 6 will be going into the donor and resold.

any help appreciated.

Crank Angle Sensor, pretty much tells the ECU when to tell the plugs to fire if I'm not mistaken, or something like that. It control the spark pretty much lol.

Imo the search on these forums is pretty half assed, I usually google "Vl running rough justcommodores" so it finds those key words on JC and you just check the threads from google, bit easier
