Re: 1993 k1500 4.3L spits & spudders during drive
hey been through all that, i have changed my fuel pump and filters, even the filters on the injectors themselves. for me next in line would have to be the pressure regulator. i changed it about 2 years ago, with some knock off brand but it is gonna keep me guessing until i replace it. i would try that next as i am too!!!
