Hi everyone! I got a 1997 E36 323i, 2.5, 6 cylinders M52, and when its hot, if I'm running, the RPM goes down for half a sec, and if the same happens when I'm stopped, it'll turn off... After this, most of the times (not always), it appears to work only with 5 cylinders I guess (have characteristics of a flooded carburettor)... It's not working good, but only after this... All this start after some time in heavy traffic... Till then its working perfectly! I changed the spark plugs, it's a bit better but it still doing the same sometimes (less frequent I guess). I'm now trying to check the coils (and I'm waiting for one in the mail), but it's difficult because its not happening all the time, and I have to check it only if it's doing it! I'm checking the coils by unplugging one by one to see if I can hear any sound change... Till now it always change, like it should, but I'm convinced that it must be one of the coils anyway... Am I wrong? Works fine when cold, so I think the option to check it with the multimeter is not an option??? Or can I check it anyway? But when cold its working really great! If I should check it cold with the multimeter, which pins should I check? Also, I think the coolant was low, so I added some (probably a bit too much... I hope it will flush it out!???), because it can also be some air in the cooling system????? I squeezed it and tried to take out the air... Haven't see any coming out, so I guess its ok... The best description I read was this: "Symptoms of a Faulty Ignition Coil One of the most common symptoms of a faulty ignition coil is when the vehicle runs for a while and then the car's engine suddenly dies for no apparent reason. This occurs after the ignition coil or module gets too hot, and usually will correct itself after the engine module cools. In some cases, a bad ignition coil will result in the vehicle not starting it all. Or, it may have characteristics of a flooded carburettor, where the vehicle runs very poorly or jerks and stops erratically." http://www.carsdirect.com/car-repair...-ignition-coil Please help! Thank you so much in advance! Best regards Note: I hope I made myself clear about this... My English is not the best...
