Check the Blue ECT sensor itself - easy to damage it or the wiring when removing/refitting the head. Also check MAP sensor pipes etc.

Any other symptoms, like smoke?

lots of black smoke lol.
all hoses are fine and all wiring seems ok to everything. how do these sensors damage so easlily? neothers?

Lots of black smoke suggests either ECT or MAP sensors, had the same problem on mine a while back - was a bitch though, because they were both failing intermittent

ECT sensor is cheaper of the two, so perhaps change that first?

will try the ect tomo as i have one i can use. as for the map sensor i looks like it has been fixed at some point where the thing has snapped off, but do u think just alittle knock would do it?

Mate, I had a Sapph' that had the same bodge (which obviously at the time I didn't realise) but it eventually failed again..... it's highly (imo) likely that's the issue, but as it's been 'repaired' before, I'd personally change it anyway.

Good luck.
