LJ 0 Posted May 7, 2004 Guys The ISV on my G60 clicks about once a second with the ignition on and the engine cold. Does this mean it or the ECU could be dud? A comment on the Vortex forum said it was likely the ECU could be knackered.... car starts but seems to run rich looking at the plugs. Once the engine is warm it no longer clicks. I've cleaned the ISV and refitted and it's still the same :-( Could it be effected by dead sensor???? This has had a neglected life by the previous owner.
