right, okay i'm going to give you the full story, and hopefully you can help me out.
When my 309 gti was on the road, in the mornings, when cold, it wouldnt idle, it'd start then cut out. only way to get around it was by blipping the throttle till it was warm. also, when it was warm, it would idle high, but if you opened the bonnet, you could push the throttle back a touch and it would calm down again.
PRESENT DAY
Cars been to pieces for valve stem seals and a head gasket, now its all put back together it'll start and idle at about 2k rpm for about 20 seconds, then cut out if you don't keep on the throttle. Mt lecturer reset the throttle butterfly and it is all cleaned out. I have also double checked the timing by pegging it, and i know the dizzy is in the right place because i scratch marked it. I haven't changed anything critical like cams, it just has a different exhaust and a re-routed intake and k & n.
When i put it back together i noticed the pipe from the ICV to manifold had been crushed, i warmed it up and moulded it back to shape so that hopefully now has flow.
I have started and (attempted to) run the car with the ICV plugged and unplugged, but there was no difference.
Any help guys? starting to run out of ideas.
It's a 1.9 8v btw with a D6B engine code.
