Hi just put a 2.0 Silvertop into my Mk6 replacing a 1.8 which had a lack of compression on one cylinder. All went well and even started up straight away, but it wont idle. everything was swapped over from my old engine to the replacement block and head but I cant see the extra 200cc would cause the lack of idle, can it? there also another mystery on the side of the coil pack holder is a small white unit which I cant find any details of - it has a two pin connector on it, however I can find a plug anywhere under the bonnet that goes to it, just a single wire close by with a non-factory female spade connector on it. Would this not being connected be the cause of of the non-idle? Any help apricated Terry

My names Terry and I have owned a MKVI 1.8 Ghia Cabriolet for around 6 years now and it goes everywhere with me and my partner Jule, even camping trips to Dorset. Its not my first, I had a MkV facelift fitted with 2.0litre Zetec and before that and early Mk5 with a 1.6 CVH. And as an Ex- Ford Dealer salesman I sold loads of them and ran a white XR3i as a demo car for almost a year. I have just, with help, swapped out the 1.8 motor for a 2.0 in my current car which I am happy to share with anyone one here about the experience, its running but I do need help with a couple of issues which hopefully some of you guys can answer, and will post in the tech sections. Cheers Terry
