M40 318i - uneven idle when warm

[FlashBastd]

Ok, I should point out that my car may have taken some water up the air intake during the recent bad weather. It runs fine, except that sometimes when warm, it hunts for around 30-45sec. This isn't a big deal, it is just going from around 750 - 1100rpm, and I would like to sort it.

Thanks for your help.

Anyone got any ideas? Having read a number of old threads, I am going to get some carb cleaner and do the TB and the ICV, and check the rubber pipework for splits - but can anyone tell me where the ICV is, and if I am barking up the wrong tree?

Thanks!

ICV is inbetween the intake manifold and the bulkhead. It presses up in to the underside of the manifold. careful you don't push the rubber gromet into the manifold when you refit ...
