I installed a used 5 speed transmission in my tiburon and when I first started it the idle problem was there, it was fine when I started the trans. Replacement, I had replaced the tach/speedometer gear and sensor in the replacement tran. With the one from my old tran. Also I had the ignition switch on when I hooked up the battery post. Would a surge from hooking up the battery mess up a sensor that controls idle? Any help would be greatly appreciated.
