1.2 Won't Idle & Coil Light On?

[Faxo]

Ive placed a bid on it at auction yesterday, but before i agree to the sale (the reserve is a few £ higher than i bid), i wondered what this could be?

Basically it wont idle, it drives and revs fine, but cuts out if you let the revs drop?

Any ideas?

Most likely either the coil pack or lambda sensor
