My 740 GL now is presenting with poor cold start (after replacing cables , sensor, relais, plugs, fuel filter battery, alternator).
Regina Fuel injection. Strange enough (I noticed this many times) the car tends to start when letting go of the key, while still cranking). As if there is not enough current available , which is not the case with new battery. The old plugs (5 months) looked terriblebut this might be my cleaning effort spraying carb cleaner in throttle body. Can it be the ECT input to the ECU? With warm weather the car starts fine , but has a hot shut down if soaking or starving occaisionally. I love the car, but this is driving me crazy.
Any suggestions welcome.
