I have purchased my first Porsche Boxster and happy in general until recently.
Yesterday, out of the sudden, I noticed the car was missfiring after taking off from a stop light. It was rattling in low revs at the beggining, then at iddling as well. The check engine light started blinking, and a minute after it turn on solid orange color. I didn't drive the car more than 5 minutes until I found a Porsche Mechanic in the area. When the mechanic checked the car, the system diagnosed multiple missfires in all cylinders but #5. That raised my concerns, since I thought it was not normal to have all cylinders missfiring suddenly, at once. The mechanic asked me about the history of the car, and I told him that I have recently purchased it, and drove it around for 3 months/ 8000 Mi, with no issues whatsoever. I have only changed the oil about 400 miles ago, at 7000 Mi as directed. It had Mobil 1 synthetic, don't know the grade, but replaced it with Mobil 1 10W-30. considering this grade would work better with the hot summer in paso Robles, where i live (temps are average 100-110F at this time of the year). I have changed the oil filter as well, and only thing I know is that the car needed a service for Spark plugs and coils at 140,000. The odometer reads now 140,500 and I was about to take it to a Porsche Mechanic soon. So I thought this would be the problem, but just got a call from SGS Independent Porsche Service in SLO and they haven't been able to fix the issue. They took one spark plug off and the ignition coil to inspect. The y have found the plug was worn out but still working well aparently, the coil showed carbon deposit but again, in working condition. That is all I know about my car and today is Saturday so the shop is closed until Monday. I decided to sign up here, and post my experience and share with the forum, hoping this will help myself and others.
I do not know the Mechanic and I am not sure if they will try to reap me off with the repairs. I am not from around here, and I have been ripped off before, so...
A word of advise would be highly appreciated.
Thank you for the attention and interest in advance.

last edit: the car was running on reserve gas, I forgot to mention. One of the mechanics performing the computer diagnose, advised me to go put some gas, which i did immediately, then I returned the car on their lunch time, drpped keys on mailbox and left home. I was reaserching on the forum that the computer on car may need a few minutes running to get all the new data, and thought maybe this could solve the cars issue. Then the shop would charge a few extra hour for the labor. Not trying to sound paranoid, buy hey....it is a jungle out there!
