1998 996 Replaced AOS and now it won't idle.

I just replaced my AOS and have gone for a drive to blow out the oil from the exhaust that made its way there when the AOS failed. However the car just won't idle. It's not that it's a poor idle, it's that it simply won't idle at all.

I've tried blocking a few of the vacuum hoses to eliminate them, and have cleaned and checked the function of the idle air valve that's attached to the throttle body. None of this has made any difference.

Obviously I'm concerned that there is a massive air leak somewhere behind the throttle butterfly, but I'm not keen to go there until I've checked out everything else. I'm also going to try changing the plugs as they were massively oil fouled from when the AOS let go.

If anyone has any ideas of what to look at next, I'm keen for your input.

I guess what I'm asking is this: Is there an electrical cable/wire/connector somewhere that would cause the engine to die instantly at idle speed?
