RamAir Fitted Idle Issues

Hello

Last weekend i fitted an oversized RamAir intake. All went smoothly and all tight and secure well it certainly feels that way. When i start the car idling is fine but after driving for 10-15 mins it now idles at 1100/1200 RPM. Also if i do a tiny blip of the accelerator it rises to 2000 RPM then falls back to 1100/1200 RPM. However if i then drive slowly for 5 mins it might idle back at its normal 800/900 RPM.
First thoughts were PCV or DV along with boost leak. PCV checked by pull the dip stick out and it almost stalls so ruled that out. Can't see if the DV is faulty but it was replaced when i bought the car 1-2 years ago. Checked all the jubilee clips apart from the one right down at the intake but we ensured it was really tight when fitting.

Thoughts please. Once i have this fixed it remap time and i want that soon.

go over the whole install of the ram air make sure you have put the jubilee cips over the pipe and make sure it is nice and tight, also take the maf off and give the port it goes into a good check and clean make sure when you put it back in it seals properly and pushed the weather seal down.

also when your car is idling high have you checked to see if the maf is dodgy

DMackie:
Im gonna check the clips again tonight. MAF was new a few months back. Ill remove it and make sure the pipe doesn't have anything in it too.

Also near my work there is a garage who can perform a smoke test which will tell me if its DV or my boost hoses. I suspect boost hoses as it only started this after the RamAir was fitted.

this might be of help to you about the Leak in air intake system, would also explain the system to lean at idle (dont quote me on this i might be wrong).
