The use of K&N type filters have been known to give the MAF sensors a hard time as the oil in these Filters can contaminate the sensor. If you have one of these Filters, I'd replace it with a standard papper one.

After having great time with my 97 Boxster for about 1 month, the hard starting problem comes back
I bought my baby to Porsche dealer yesterday and they call me today telling me the Mass Air Flow Sensor is bad. It will cost me $500 for part and $300 for labor. Do you think I can replace the sensor myself? Should I try replace the filter first and see if it fix the problem? Please help!
