Is it hunting idle? They are all a bit rough on idle especially when cold.

Yea that's right bit annoying the revs go up then fall the Rev counter does not move though.
Maybe thought it was a fuel thing.
Where is the filter.

Filters is behind the wheel arch by the pump. I don't think it would be that through. Quite often it's just the throttle needs adjusting. On the back of the throttle body there is a long screw (10mm spanners head from memory). Just give this a quarter turn either way and see if you can get it to stop. Only needs very small adjustments. If it's not it then it tends to be a manifold air pressure or adaptive map thing. People who reset their map often find the problem stops but try the air mixture first!

Mine did this for years. In the end Dave at Jetstream had to program one of the lambda's out as nothing else would sort it. It's been fine since.

Hi Tuscanny,

Just wanted to say Hi really, not very helpful I know, but I am a new owner myself albeit I am still waiting to pick it up (engine is out currently), so was curious (and envious to hear you got yours today). Did you find it relatively easy to find a car or have you been looking for some time? looking at the pictures you have posted it looks to be in great condition but I don't recognise it (from an advertisement), did you buy it here through the Noble forum? I have tried on and off for several years and it never seemed to get any easier (and the cars never got any cheaper despite getting older!), so took the plunge.

Not sure I should be just chatting generally on this thread, if not my apologies everyone..............

Chris.

Hi Chris I have been looking for a few months now and my Tuscan sold.
I seen this one on pistonheads advertised in Germany. It's still on UK plates so made bringing it back easy.
It's a low mileage low owner car 17000 miles.
Just got the mot done today and the manifold is blowing is this still ok to run like this .
Must say it still drives great but don't want to cause further damage.

One of the guru's will give some advice I am sure, There are some seriously knowledgeable and skilled people on this forum, I honestly would not be able to advise you. I thought I went a long way to buy mine in Stevenage! Did you drive it back from Germany - must have been a hoot.

Hope you get the manifold sorted - can't wait now to pick up my own car.

Do you mean the manifold is cracked or the gasket is blowing?

Can't tell can't feel a crack it's like it's blowing from the front of the bottom manifold.
If it was cracked how would I know .I can hear it blowing but awkward to see.

Mine is an early 3 and all the idle issues were sorted with a remap. Cleaning and adjusting the throttle didn't help much.

I've fairly recently become GTO3 owner too. (Since May this year) and very recently changed the rear manifold due to cracking. Didn't know it was cracked till I took the turbo off.

Put a new SS one on but was a bit shocked at the cost.

Fingers crossed its just the gasket. Can take a pic of the cracked manifold if it helps

Thanks all I hope it is the gasket TrackMonkey I can't feel any cracks .
It'd blowing on the bottom manifold at the turbo side .Anything to consider if I remove the manifold does the turbo have to come of to.
Can you send the picture.Thanks

Started the nobel up this morning and from cold it does not blow and ticks over fine .
Once warm it starts to hunt and blow from the joint at the turbo area.Would this suggest a gasket rather than a crack.
Thanks again .

Sounds like when the crack opens it messes up the air fuel mix and the lambda tries to correct for that and it starts hunting?

IMHO, if you need to mess with the idle screw then there's something else amiss. It shouldn't need touching on these engines.

Mine used to idle fine at cold but once warm would start to hunt! Cracked manifolds front and rear frown
