Hi

I've got a stock A12 in my ute and its idling up and down somewhere around 900 - 1000 RPM while on neutral feels like its going to stall.

Then if I drive it drives fine but stalls slowly when in neutral or slowing down/stopping on 1st gear.

I have to keep my foot on the accelerator to keep a higher rev so it wont stall.

checked timing
adjusted the idle and mixture
checked the fuel level in carby and its spot on the centre.

replaced spark plugs, distributor contacts, rotor

Please advise

thanks
