hesitation 3.8 98 mustang
MY 3.8 98 mustang has a noticiable hesitation at 45mph and a slight hesitation at 60mph. I changed oxygen sensors but had no improvement.

Re: hesitation 3.8 98 mustang
Did you check the DPFE/EGR system? The EGR valve/tube can get clogged or the DPFE sensor clogged/moisture built up in it and both can cause this.
