Hey guys i have two questions for you. The first one is, I have an 05 lincoln ls v6, and wanted to know how difficult is it to replace the pcv valve? Do I need to replace the elbow with it or just the valve? I have a good idea where it is located on this car( i hope so), after hours of googleing pictures of the engine online. Question #2 When i start the car and put it in drive, it will surge forward just a little, was wondering what could be the issue? I have gotten, all plugs and coils replace fyi. Thanks
