i had this same issue in my 90 944 s2. it was burning so rich. plugs were black. then the idle starting going up to around 1500 then dropping back dow to where the car would almost stalling. back and forth for a while. i pulled the vacuum off the fpr and fuel what jump coming out. i replaced the the fpr. and still wasnt running right. then pulled the vacuum line off the dampener. and same thing. fuel was coming out. then replaced the dampener, and car runs great!!

so in the 911, i pulled the vacuum line off the fpr, same thing fuel was coming out. plugs are all black and running rich. all the trouble i had pulling the fpr out of the 911, i thought maybe just start replacving vacuum lines and fuel lines too and the dampener. i had the car since 2003, so im pretty sure everything is probably original.
