Here's the deal... Went out to start my truck - '88 TBI 350 - to go home from work the other day. Truck starts up fine then all of a sudden lugs way down rpm wise - guages and radio go haywire and it stalls. I say. So I try to start it again - truck starts and now I smell a hot/burning electrical smell. So I shut it down and open the hood to find the positive cable from the battery to the starter "welded" itself to the heat shield on the manifold. I disconnected the neg. cable, pryed the pos. from the shield, taped it and re-routed it. All was fine before that - but now I have a misfire upon starting it cold. After it warms up, it idles fine. Would/could a short like this affect the ECM or any sensors? No SES or codes set. After new plugs, wires, cap and rotor it is still there. Any idea's?? Thanks in advance!
