So cleaned the iat and found my hose was about halfway off the throttle body and there was oil down the pipe and sat in the throttle body itself. Can't see any holes in it. Also oil all on my bonnet.

Ah-haa, seems it was working it's way loose. Not sure if that's too much oil in that area? I think a thin film is expected, hence the need to clean throttle body. If it's been like that for a little while that may explain the amount. If you need one I have spare oem cooler to TB pipe. Seems you've found the culprit, certainly wouldn't help idle or boost.

Just took it for a spin. Seems to be surging less but still there in 5th. Seems to be above 90 now instead of 80. Idle is abit better too. Still the needle moves up and down a fair bit. I noticed it was working lose abit again. Maybe the oil on the inside of the pipe. Should there not be that much oil? I wonder weather to take the cooler and clean it somehow?

It's hard to say without seeing it but it looks like more than I'd expect to see. I don't know what slightly excessive oil there signifies, sure someone here has a suggestion. Did you clean the throttle body while you were there?

If there is excessive oil there it will be getting dragged up from beyond the cooler, pancake pipe etc

No got no cleaner to do it. Only got brake and contact cleaner in atm. Suppose I could get some carb cleaner and clean the tb, pipe and the pancake.

Yeah you can rule out dirty tb then, or that may even be the issue.

Do you remove it or do it in place? Iv sprayed it before when it was in place about a year ago

I left mine plugged in but unbolted it and sat it on a small plastic tray. You can leave it bolted on but be careful spraying into the manifold. Get a replacement gasket though too. Get a helpful wife to put ignition on and press throttle to open the butterfly to clean right through.

Have a good cloth to get all the crap off n all. As you're doing it may as well get it spotless

Do you reckon it's worth changing this coolant sensor too?

Could do, another thing to rule out although the symptoms you've got don't entirely sound like CTS problems it can do some weird things if it's starting to fail. They're not too expensive and it's a diy job, just need a bit of a coolant top up but you won't lose much.

Thanks again

Oh put that bootlid on a few weeks back. Was alot harder than taking it off lol. Looks ace now tho

Yeah I thought it might be a bit of a handful, and putting the loom in was always going to be harder than whipping it out, worth it though! Nice one. It's quite nice thinking that some of the body panels are still out there lol. Andy68 had the front bumper in the end.

Cleaned the throttle body and replaced the gasket. Made no difference. I remember when I first got the car I half removed the intake manifold and never replaced the gasket. I literally pulled it off the head slightly then put it back together. No idea why. Could it be possible iv got a air leak there or would it be unlikely. Other than that what else can I try? That temp sensor thing is £30 something brand new so don't want to just change it unless I got no choice.

Would probably be worth trying a gasket there and torqueing the bolts properly. If there is something slight there it would show up more after a remap with the increases in load and pressure. Like you say leave the cts for a bit, probably until more symptoms reveal themselves.

Have you spoken to Shark yet? A smoke test and/or some data logging would be very useful. See what the duty cycles and sensors are doing around the point of the problem.

Iv been back once. I then had surging in all gears after it was tweaked. Now I'm back to 5th gear surg after another tweak. I'm trying to book in again but it's getting the time. I want the to do it on the rolling road and sort it out but I bet there going to want more money to do that. Problem is I can't achieve the speed till I'm on the motorway and it's pretty built up around shark.

Yeah you need the rolling road for that one to get the logging results. Have you tried a smoke or pressure test yet?

No iv not. Not really sure where to get a smoke test done.

DEFO NEED TO DO ON ROLLING ROAD 

Well iv msg them about the rr but no reply as of yet.

I had a turbo pressure test done and the crank breather was leaking i'd ask shark if they can do it or smoke test it , save you and them time

defo easier to call

That's a case of ringing round locally and seeing who has the equipment. It's not a specialist job as such it just depends on whether they've got the stuff.

I'm still surprised it wasn't solved when you found that issue with the pipe onto the tb. How is that now?

It's fine now. I wonder if it just wasn't done up tight and with more airflow it pushed it almost off. Yh might see if shark can do a smoke test.

Just spoke to shark and it's booked in for Monday. Asked about the rolling road and he said it's very unlikely to show up on it so not really worth doing.

Tried my mates n75 valve and still got rough idle but didn't get high enough speed to check I'd it still was surging but I'm guessing it would of as it felt no different.
