My 95 Ram is still surging ecspecially when the truck is still cold. I have replaced plugs, wires, and distributor. I have done the code checks and they did not relate to my problem. Does this sound like it could be a bad sensor? The truck runs pretty good after it has warmed up, but I think it is still not right. It just seems sluggish. My next step is to have my local shop hook it up to there computer and scan it.
