I take it you have the 4.0 engine then?

The new CPS will only be a temporary fix if it's plug and socket are
dirty. The new one only replaces half the trouble, the other half is
the socket on the harness....

I really would recommend you just clean it first. Even WD40 will work
as a cleaner on it's socket.

When mine was quitting, the CPS clean didn't work, neither did a new
one. Mine turned out to be a rotted mesh ground strap that runs from
the engine head to the firewall.
