I have been having a read on the web & the problem that I seem to have is that the current waveform, is not as listed for peak & hold type injectors. My current trace is a low peak hashy one, varying from injector to injector. On the 1994 Jaguar XJS 6.0 the injector connector is a 6 way connector sited on the innner O/S front wing. I suspect that I may have a high resistance connection. I will be carrying a fully EFI wiring loom check, using the scope.
What I have presumed that if the injector is not receiving the correct ammount of current, due to faulty loom connectors, then the injector is not opening properly, therefore no administering enough fuel. This would cause a lean misfire. The EFI system would then increase the injector pulse width & place more fuel into the exhausts, unburnt fuel, which is causing the rotten egg smell, that I am experiencing.
Am I on the right tracks
