At idle and or on the road I feel a miss while slowly accelerating. Not all the time but when going up a slight grade and in “cruise” at speeds from 25 to 65… also while at a stoplight I get what feels like a hiccup…doesn’t feel like lack of fuel but more like electrical. 95 Yukon, 5.7TBI. Replaced plugs and wires, no change but am radio works w/o buzzing now.
