Thanks mate! - I took the airbox off and had a look at the cable and it was slack and still slack when I started the engine. so dismanted the IMRC and moved the cream cog thing from under the circut board a few times and put WD40 all over it and the cogs which were stiff to move beforehand. and now no more engine light and so much more torque at low RPM!! Only thing now is I can hear a constant knocking noise when stationary. hard to work out where it is coming from. Just had cambelt kit changed so not that
