Hey all. I need your opinons. I just changed out a few parts on my 93 XLT and after getting the firing order correct on the wires everything seemed to run fine. The wires are where my question for you all lies. The truck ran fine like I said, but only for a short time. After a few hours of driving it started to surge occasionally. I brought it by the shop I bring it to, and my pal there wiggled some of the wires near the caps and the surging of the engine evened out. So intermittent wires...right? The wires are Duralast, and after purchasing a new set (yes I returned the old ones after install) and installing them I tested the old ones for continuity. It seems that 2 of the wires were broken internally. So now I'm driving on the new wires and the same behavior (I really want to call it Surging Engine Sydrome) begins to occur and power drops out. I'm considering getting the Bosch Wires from Autozone because they use the high-temp silicone jackets. Would this make any difference? Could the wires be failing internally because they are Duralast and are poorly constructed? Thanks all!
