Re: engine dont start
Don't apologize - my Polish really sucks :-)
Have you checked the spark plug leads? They are made with a carbon-coated string that is brittle (breaks easy) and often fail.
Also, I have had new plugs with cracks in the ceramic that would not fire at the tip.
If you take each plug out, one at a time, connect the plug wire to it and let it rest on the block or valve cover, you will see a spark or not.
If not, then either the plug or the wire is bad.

You could have a bad injector, ohm the resistance of each one. they should all match. I am thinking maybe 14 ohms but could be wrong, check specs for your car. you need to at least narrow down which cylinder then check for spark on that cylinder while the miss is happening. some of these 3.8 engines would melt the plastic intake manifold at the egr passage and leak coolant into the cylinders, are you losing coolant?
If your getting a P0302 ( cylinder #2 misfire detected), the first thing to check is the spark plug. If it's new then the next thing to check is the plug wire. If it has individual coils, then swap it out with another one and see if the misfire moves too. If so then the coil is faulty.
Hello you will now need to disconnect the engines battery using the proper sized wrench or socket.Ounce you have disconnect the battery for a couple of minutes now reconnect the battery this should reboot the engines computer keep in mind just like at home on your PC when you install new hard wear you must restart or reboot your computer for the hard drive to recognize the updates and hard ware.
no flashing light and rough shaking will be part of spark plug but also a very bad miss fire. I am going to guess that your engine is a 1.8t if so you have 4 coils that sit on top of your spark plugs that most likely are arcing you will need to figure out which coil is failing or you can save yourself the trouble and replace all 4 and the spark plugs. before you do that though check your wireing going to your coils look for broken wires or the ground that is next to the #1 coil that is the one closest to the front of the motor and you. hope that helps. that will be the start to fixing your issue also when you pull out the spark plug look down the hole first and make sure that there is not oil in the bottom of the hole if that is the case you will need a valve cover gasket as well. good luck hope that helps
ihad the same problem.. its not the coils or anything like that.. and any reg mechanic wont know the prob unless they under vw.. u need to replace ur power output stage.. thats what cylinder 3 misfire is.. after i fixed it my car is good as new. i
