Ahhh Keygatzo! Unusual shaking, running irregular, possible MAF, lots of threads to read about it. The MAF has tamper proof multi point fasteners, just so you know, you can try carefully cleaning it. Error codes from the OBD port under the light switch would definitely help direct you to the source. I'm not certain but an O2 sensor not reading right might effect idle too. In either case you get to live in Italy so there is a silver lining!

Without scanning the DME, anything ventured is pure speculation; get the codes read.....

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...

Jack, Porsche introducing it's customers to what in might be like in a men's prison shower is not the exclusive province of Italy. Get the codes, readers are pretty cheap on the net, if you plan on any DIY it's a good investment along with the Bentley book, good luck.

A blinking CEL generally means something catastrophic is about to happen. Even if it went solid I would' go anywhere until you but it on an OBCII.

100% agreed. It's in your owners manual. If the engine warning is flashing, you need to immediately pull over and get the car towed to a place to get checked and fixed, or risk doing serious damage to the engine.

Like others have said, get the codes read (DO NOT START IT), and use those codes to get an idea of where to start looking for what's wrong.
