Rob,
I dont know if you remember replying to my post entitled "ERATIC IDLE ON START UP", but can i just say you are a F*ck*ng star!
You were unfortunately right about the head gasket having gone.
I tried my hardest to prove you wrong. I thought of everything, form the plugs and leads, dodgy lambda sensors, ECU problems, fuel pressure, injector problems, the list goes on and on. But the one thing that kept coming back was the head gasket.
I changed it and when i took off the head i found a nice puddle in the two centre cyclinders. The plugs and valves where white like xmas, looked nice though. lol
Anyway, just wanted to say cheers for the advice, all is well now, it purs like a kitten and starts like a dream
Cheers,
Mr Winkey
