Thanx guys... I 'think' I sorted it, it's fine for now.

In a nut shell when I got the car running I sprayed WD over anywhere where I thought there could be an air leak, and there was no apparent leak, so I checked the connectors again, disconnected the ISCV and Maf, as soon as I did the car cut out straight away, so I guesed it wasn't those.

Delving a little deeper when I took the inlet manifold off there are to nipples on the throttle body one is blocked off, the other has a pipe that goes the the fuel reg, I swapped the pipe over thinking I 'may' have replaced it on the wrong nipple, and when I took the rubber cap off the second nipple it literally fell to bits... I did a temp repair with some insulating tape, and so far so good. So i'm guessing it was a massive air leak cuased by the rubber cap being fukked.

Thanx for your suggestions tho guy's I appreciate it
