x2. And be sure that all of the vacuum lines, etc. in the area are correctly and securely attached when you're all done with the replacement. Don't ask me how I know this ...:rolleyes:

Cleaned mine and it still failed. Connected to 12volt power and it worked. Took a file and cleaned to post, now it works fine.
