Grand Vitara FT (EZ 2002) runs on three cylinders

Hello, at the Grand Vitara 1.6 (7102 / 381; 1.6L 69kW/94PS) of my girlfriend, there are the following problems – hardly pulls anymore -runs while giving gas on three cylinders and shakes accordingly -has thirst like an ox in the desert. – smells in the exhaust gas after unburnt petrol At the tester he had deposited the error “Fleistung Kugel 1”. Findings/measures so far: -ALL candles are black, slightly moist, have been replaced. -AGR valve cleaned, stands in position closed, with subtracted S no change. -no change in case of disconnected plug from the LMM. -both ignition coils have been renewed -compression ok, on all four cylinders equal to +/-0.5 bar. -crankshaft sensor renewed. -refrigerant temp.-gender has comprehensible values on the tester. -voltage curve of the Lambda control probe looks correct. (screenshot) -petrol pressure regulator changed -at the moment at ease. 🙁 ….and grateful about any idea. Greeting Björn
