Re: broken it again! grrrr. injector light and no power
well, very nice man from the RAC has just been round (good job I joined 'just' before the car broke down), and having come up with no issues on the diagnostics test, pinned the issue down to a dodgy connection on the throttle potentiometer at the pedal end.
annoyingly, he could remove the ecu to get full access to the connection (to clean it out and plug it back together), so could only give it a good wiggle about... it fixed the fault straight away... so i now know what the issue was,,, i just have to hope that this has fixed it... otherwise it's off to the garage to be taken to pieces and sorted once and for all.
apparently, it is quite common for throttle faults not to show up on a diagnostics test.
