I purchased a 95 Accord V6 that runs great, but the tachometer is always at 0. The check engine light is on with a P0725 error code. I did some google research and read this article that suggests I replace the ignition coil:http://findarticles.com/p/articles/m...i_n9079886Only thing is that the article mentions an "erratic" tachometer, not a broken tachometer. I also stumbled upon a forum thread where people were discussing success at fixing their "erratic" tachometers by replacing the coil. I really don't want to shell out $80 for a new coil only to find that my tach is still sitting on 0. Is there anything I can check on the car before I purchase a new coil?
