Runs rough

Asked by May 05, 2018 at 10:40 PM about the 1985 GMC C/K 1500 Series C1500

Question type: General

My truck has 305 engine, replaced 2
plug wires cause they were arching on
exhaust manifold, then it ran fine for a
couple weeks, then back fires and
rough running again, so replaced all
plug wires, still running rough and back
firing. What can be wrong now?
