I recently changed from long tube headers to short engine swap headers that would allow the exhaust to hang a little lower and clear the frame rails. Since the change, I now have starting issues. Prior to the swap the engine would fire and after a little coaxing would idle on its own. Now it acts as if the battery is bad. I had it checked and was told that the battery is fine. I took the starter in and was told it was okay as well. Today, while trying to track down the problem, I notice smoke rising from the throttle linkage while I was trying to start the car. The linkage was hot enough that I got a nice little blister on one of my fingers when I checked to see what was getting hot. Has anyone run into this kind of thing before? I have checked for wires that could be in contact with the linkage, but have found nothing. Any advice would be appreciated.
