I have 63K miles on my base 987. Yesterday my check engine light came on. Went directly to my favorite Porsche garage and after hooking up the diagnostic tool indicated my MAF had thrown an alert but the code was no longer active. They indicated this wasn't uncommon, turned off the alert and suggested I just drive it until or if it returns. The car was running very well when the light came on and has been running well since the code was deleted. They were very busy at the time and graciously fit me in so I didn't spend a lot of time on whys and wherefores. Is getting false of erratic MAF errors something that is a precursor to the sensor failing or is this just something that happens occasionally? Is this likely to get me stranded on a back road or do serious damage or is it ok to drive it for a while after it comes on again. I live in New England and was preparing to store the car for the winter but we have had some unusually good weather so I was getting a little more driving enjoyment before putting it away. Would rather fix it if it is broken before I store it for the winter but unsure if it is really safe to drive any distance at this point. Input on MAF errors would be appreciated.
