My bro has a VR and has been converted to gas. He had some problems with the gas conversion when bought from holden and they have now replaced the whole system and works very nicely. However, on the last day of warranty, they replaced the oxygen sensor just too make sure everything will remain fine. But now in fuel mode, the car has a very low idle and has stalled often in gas in Park. However, gas idles very nicely. Anyone got any ideas? I was going to adjust the Idle Speed if i knew where that was aswell - anyone know whwere it is? coz it aint on the computer like in the vl's cheers for any help

if the car was tuned for gas it will always idle roughly on petrol. and if you tune the car nicely for petrol, you will have the same rough idle when on gas. you have to tune it in between, but that will result in bad fuel economy on both petrol and gas.

arh okay thanx stageIII i have told him that but i dont think he believes me fully is there an idle adjustement anywhere though? lately, my vp has done a couple of stalls like putting into into Drive from Park and putting it into Reverse just tonight. The fuel pump was just replaced but it did it a couple of times before that...
