Have u tried looking to see if any CEL codes ? nah silly question u must have.
Water temp sensor ?? temp sensor says engine cold and tells ecu to give it more fuel and revs ?? ( or summat like that, better wait for the experts )

Just had a thought... have u tried an ECU reset

 

yes im sure its been reset took it to falkland performance it had not been reset the last time it was in another garage so they reset it but still that problem i mabye tell them about the temp sensor u trhink that might be it then

 

Here's an interesting thread http://bbs.scoobynet.co.uk/showthrea...ght=water+temp

U could check out the TPS (throttle position) , not gunked up
Water temp is a long shot i reckon
