You probably just need to set up your tps correctly.
But it's never been touched? It's still got the paint on it from factory. So it might be failing.

well my radiator top tank spit and i think the steam jet went into the air snorkel[because of under bonnet spray pattern] and f,d the maf thing ; resulting for will i or won,t i get home/ the rubber seal thing has basically gone on mine/ is your seal intact where it bolts on to the top of the radiator could not even see the split until i did a run arond the block [a week later- just to see you know] and wiped the top tank and seen it weeping out . is your water reservoir coolant thing dropping? - i better go and cook food now

found that sweet spot for TPS is 13.7% (done this on Dan's car)

originally thought 11 or 12% but car goes into stall mode then goes back into normal idling after..

What is the mV reading at 13.7% I readjusted my TPS after doing throttle body seals using works scan tool but only reads mV, did improve a little but still does it a lot.

Tps should be 13.3333%. No idea what that is in voltage though

You sure. I thought there were dead bands at either end?

Thanks Guys for the suggestions that gives me a bit to look at.. (my boost control is a 3 port managed by the ECU.. but yeah it happens off boost mostly..)

Update - i replaced the IFS (Ignition Failure Sensor) on top of the front rocker cover (about $40 from memory) and the stutter problem hasnt recurred - its been ok for a couple thousand kms now.. very happy. (Thanks Trotty for that suggestion)

just to close this, nearly 1 yr later and still no stutter so IFS was definitely the fix

They are funny nuggets of things. My car is now doing this again.

I think mine has just gone. Where's the best place to source them?
