reduced engine power light

Model: Cayman S, Year:2009, Mileage:7700, Type of use:Street use only
1st car was difficult to start, requiring multiple turnovers. When it finally started, the "reduced engine power" light came on. Next day, the engine was difficult to start but finally started, during driving the car would not accelerate and the "reduced engine power" came up again this time along with the yellow engine light. What's causing this? Battery is fine, the car is currently in diagnostic at my dealer.

What is the function of the Air Mass Meter and how can it get damaged to the point of needing replacement? The car was in an accident while at a stop and was hit on the driver side door. Prior to the accident the engine was running fine.Thank you,Robert

Engine coolant

Model: Boxster, Year:2004, Mileage:15000, Type of use:Street use only
I read all the posts in the engine category and have a question about the coolant.Porsche calls its coolant life-long, however after checking the PH in my car, I found out it is at 7. The PH of new coolant is 8.3 ref: Material safety data sheet from Porsche. It is obvious the coolant in my car is getting acidic, so why not change it then?Thank you,Eric

My check engine light went on after my wife put gas in the car and did not properly close the cap. What do I do to get the light off.

On a recent trip to CO and UT in my 2002 Boxster, I discovered that all the fuel in those states has "up to 10%" ethanol. Will that hurt the engine? There is no way to avoid it.
