Hi I just received Motorcraft spark plugs for my car and I am considering doing them myself to save money. However, I have never changed spark plugs myself and I know from the forums that removing and installing spark plugs on these cars can easily cross the threads, have spark plugs blow out later, etc. I do have the correct Haynes repair manual and I am trying to get the confidence to do them on my own. But am worried that I will mess something up or have them blow out. How finicky are the spark plugs to remove & install? Does anyone have any tips or tricks for this procedure?
