Thanks guys, I have changed the egt and the coolant temp sensor. It's runs worse now, misfiring, spluttring, stinks of fuel, but I did take some pipes apart to see if I could see or feel any splits.
I did the maf sensor test and I'm thinking now it's the maff. I pick the part up tomorrow morning. Fingers crossed otherwise he will be sat on the drive until the end of the month.
