It's about making things harder than they are (reason for so much divorce as well).

There is nothing hard about changing the CPS. My mechanical skills are about as low as you can get, and I can change a CPS faster than I can replace an oil filter.

The mistake everyone makes is they try to remove the bolt first, then yank the CPS, or they put the CPS in and THEN try to put the bolt in. WRONG. Loosen the bolt and remove the bolt and CPS, holding the bolt in the CPS' hole with the rachet and lift it all out together - easy. DO NOT unplug the connector from the CPS till you get it all out of there.

Use the reverse technique to install the new one. With the right extension, you are done in a few minutes.
