la710 Posted May 8, 2020 Report Share Posted May 8, 2020 My new CPS arrived and since I was placing an order through Ford, I've now got a new air filter as well. Is it advisable to disconnect the 12V battery before replacing the CPS and air filter? Many thanks... Quote Link to comment Share on other sites More sharing options...
