2 weeks ago my vsa went off along with the triangle !. I took it to get the codes. Come to find out i have 3 misfires in cylinders 3,5,6 and 83-1(ecm and pcm ) and 84-1 (sensor logic malfuncfion). Last year we had the same misfires and got new coils. I think maybe they went bad after a year because last year every cylinder was going off now its just the 3. Were going to try new coils and spark plug. But I am woundering if electrial or batter could also be affecring these codes. 2007 honda pilot and we have never bought a new battery. We have replaced the transmission, altinator, ignition and sterring rack and pin before these codes came up. Anyone have any other ideas to what could be the problem? I have always worked on my cars since O was 18 with no problems. I would prefer to stay away from shops. I have to make a 600 mile drive with my kids because of watee line break and I cant be in the home while they fix things for 4 weeks.
