Engine warning light

[thejack]

Hi,
thanks for replying. MAF sensor has been replaced about 50k km ago... Already arrived its time again? I'm gonna try to clean it but I know there's not too much to do if it's him broken.

If I have to say it all, it's a long time I have been facing this issue, especially in cold weather and cold start.

Engine is shaking slow, like a missing spark in one cylinder, but after a few seconds everything was going to disappear at all and no warning lights was lit up. This morning engine shaking was a bit more stronger than it was before and lasted longer until the warning light started to blink. May be a coil or injector... But I know I need to take her to the dealer, unfortunately... which means a huge money wasting... especially in Italy where if you own a Porsche, regardless if it's over ten years old, you have to be robbed beacause of the false equation Porsche's owner = Rich man... Welcome in Italy...
