S2 mfi won't idle?!
So, after doing the clutch on my s2, everything refitted. Goes to start it and it won't idle. Checked everything, all plugs ok etc. It does start, but just won't idle, I'm having to blip the throttle so that it doesn't stall. Any ideas? Cheers

Check all your boost hose clips are nice & tight & it sounds like you've got an air leak if your still running the standard mfi fueling system

MFI is sensitive to vacuum leaks. That hose is one to check as is even an iffy oil breather cap. Which breather system are you running?

Running standard system. Noticed that there isn't a vacuum pipe going to the pressure regulator. Where should this come from?

Wahay!! I've lost my Virginity!!
Some people used to hook it up to the inlet as a crude rising rate fuel pressure reg afaik.
I had same problem as you, wasn't idle unless i nudged the throttle, boost pipe was loose.

The intercooler itself shouldn't but if the boost hoses haven't be tightened up properly that'll be your air leak causing the car to cut out
