Hello Porsche,
I can not give you advice for a long time, my car started to start with a cold engine for 5 cylinders, when the car heats up or better to say when it passes for about 3 minutes the car is running so it is good. Or, when I add more than 2,000 revs, it will go right in the cold. When the car heats up and the warm engine is still running well.
Even if I start it in 3 hours, it will still work well. The car does not need oil or water. I changed candles, ignition coils for new ones.
Do you have any idea what this can be?
well thank you
Sorry for my English, im Slovak man :/
