I have a 1996 Z71 pickup & it stumbles, & misfires at light to moderate throttle, but full throttle seems to be the same.I've replaced plugs, dist. Cap, & rotor still have same problem had it tested at auto zone & both oxy sensors showed failing. Does this sound like oxy sensor problem or could it just be starving for fuel causing the misfire & bringing up the oxy failure? I need help please!
