Cheers for the advice. And I hadn't got around to posting on here but I got the exact same advice from jimmy at alba euro. So I'm sure you are right.
Other than that. The car is doing well now. Got another couple of hoses replaced and a coolant temp sensor. Seems to be happier, except with morning starts. I've been told the fuel pressure drops over night and needs to build back up again. It starts first time but chokes and splutters to life rather than just a smooth start. Any other ideas what it could be or does this sound right? Any way to fix it?
