Good I have a Daewoo Lanos 1.5 of gasoline, I've been in three cylinders for a while I have changed the spark plugs and cables and I have still told me that it can be a valve but compression has the four cylinders I have made it manual to see the compression and of the coil you tell me that it is very difficult for it to buy it and spark You can hold a hand, it has the car crazy and I don't know what to do more thanks to hand
Check out the setting, if the compression is fine and you do not have a water baporization excess, it is difficult to be the butt, check the oil that is not emulted, but I believe that if it is not the distribution you will have to take out the cylinder head.
What type of injection does it have if you have a distributor lid can be a crack in the lid of it and if not, you may have an air sucking by the Admission Multiple Board check this before taking out the lid that is less work this is all that I can tell you I would review that in my workshop first.
