Hello professionals and hobby screwdriver, I am the André from Berlin and not exactly the professional or hobby screwdriver. I have a Renault Megane 1.6 16V with a Prins LPG gas system, BJ/ day of first registration 10.2001 – If relevant HSN 3004/587 . Read here for some time and I was explained one or the other thereby. For this thank you to all! Anyway, like many others I also have the problem with restless motor running in the stand when it runs on petrol. The engine purrs like a kitten. If I want to start the car in the morning, it needs between 3-6 runs, partly the engine jerks when it approaches and chokes again. After a few try it then catches itself and the speed goes in cold condition from 1000-1200 revolutions down to 750-780 approx. The engine runs restlessly, and from the exhaust comes then a buffer (stronger emission of exhaust gas) but no bang, in the same cycle as the engine runs restlessly. hnumber 1500-2000 revolutions, purrs the engine. At a certain temperature, the Prins LPG system switches on and the engine is completely relaxed. I turn it off or again on petrol the engine runs restless. Speed drops down to about 550-600 then goes fixed to constant 750-780 revolutions. What I have done to date: 1: throttle valve cleaned 2:Instructions changed because the old total failure had changed about 3 weeks ago. 3:Gaspedal Poti changed, because according to odb2 an error message ka m P0120 (Fig.1). Have a partially electronic accelerator pedal (gas pedal-built train engine room/ Gaspoti) 4: spark plugs changed/ from NKG diode distance 0.9 5: ignition coils changed / from Beru After changing spark plugs and ignition coils suddenly the MKL flashed. Anyway, everything was removed and controlled again, spark plugs are a bit black but not oily or damp. Ignition coils also look normal. According to Odb2 error message 0300 (See picture 2) error code I then deleted. Have the cables d I looked at the ignition coils and they don’t look fit, some of the ribbed protective sheath fell apart. I then when the engine ran in petrol operation the individual power cable which leads to the injection valves/nozzles sometimes moved and determined that on the cable to the injection valve/nozzle 4 (motor monitor left ) is a wobble contact. If I move the cable up towards the ignition coil “wheeps” the engine, I move it down the engine from and the MKL is coming and the motor is turning with approx. 1700-2000 revolutions. Wiring Picture 3. My question which cables do I have to buy or where do I get them from? Ignition coils harness? Thank you for your help and tips!
