Hi guys,
Firstly hello all as this is my first post on here despite being a member for a couple of years however I now have an issue I can't find the answer to.
My 996Turbo has developed a problem that I think has being manifesting itself for a few weeks. It started hunting quite extremely at idle to the point the revs would drop so low it would almost stall then shot up to around 1100rpm. This was very intermittent with no engine management light.
A few hundred miles later I was driving it and it became very hesitant around 2000revs (pre boost) and almost didnt want to go past that. When I forced it by accelerating hard it ran horrendously and blew both boost pipes out of the bottom of the intercoolers.
I've booked it into the garage but everywhere is extremely busy atm so there is a long wait hence this post. I did some research and suspected it may have been the N75 Valve but have replaced this and it is still the same. Both actuators are free from what I can tell. It drives fine below boost range providing it hasn't gone into that range on that journey.
Has anyone had this issue in the past? If so what was the cause? I suspect a vacuum leak but not sure where to start looking.
The car does have some mods; gtrs intercoolers, Forge Diverter Valves, 74mm Throttle Body & plenum, panel filter and map by Nine Excellence running 1.2bar.
Any help would be much appreciated ??
