Yeah, air leak somewhere.

im a little disheartened now, what could it be in my case?

If you didn't managed to get all the old gasket off that is probably what's causing it

If it's a struggle to get the remains of the old gasket off completely without damaging the head, then you can do what Stan has done and use a standard gasket either side, which'll allow a bit more flex to take up the undulations.

If it's the first fitting the gasket has had, then sometimes overtorqueing the manifold bolts by a few lbft, then slackening and re-torquing them can help seat it against any scratches/debris.

Can't work on car till the weekend but going to get two paper gaskets foe either side of Ptfe one. I may have put the odd scratch on the mating face when scraping the gasket off, do u think I should lightly sand it? Or put a bit of liquid gasket on? Will they work ok here? The scratches are small but I'm paranoid about any air leaks now so want to be belt and braces

without sounding insulting, this happened to me when i forgot to plug back in the ICV

Any suggestions? I only have tomorrow to work on it, I am going to make sure that all pipes securely fixed and try torquing down a bit more, undoing and then re-torquing. Trouble is, surely these things would only allow a small amount of air to leak in. The effect I'm getting is like I'm starting the car with wide open throttle and leaving it there!!!!

Sound, yeah I'll double check everything. Can anyone tell me how to prime the icv - I've read a few methods. So far I have just been disconnecting the battery for 10 mins

Used a torque wrench, brand new Ptfe and 2x OE fanimold gaskets

Gonna get a few hours on the car this weekend, currently riding the usual wave of optimism and enthusiasm followed by the oh so predictable crashing depression which follows another unsuccessful attempt to fix it! Got a right Heath Robinson idea up my sleeve though, to help locate the air leak I've got some smoke bombs. Gonna let one off in a something like a biscuit tin to build up a load of thick smoke. Get 'our lass' to fire the car up just as I release an almighty smoke cloud under the bonnet. Its sucking that much air I reckon it'll do a good job of showing exactly where the leak is. Only bad thing is the neighbours will probably think I've finally blown it up!

I'm thinking now either the bottom / underside of the manifold is not mating properly I.e it's catching on something or it's a cracked resonator. But I'd prefer to check first.

I had hoped it could be MAP or sensor related but I don't think they could make it rev this quickly, especially with throttle closed and icv feed plugged!

I read that About carb cleaner etc trouble us I only have a second or 2 to do it as I'm worried I'm gonna f**k the engine red lining it from cold
