Default Might have found why I was misfiring...

Let me start by saying that I was having a high rpm missfire when going past 450whp. I gapped the plugs down and it helped, but still made me wonder. Lately I have been noticing my dash flickering at idle mostly. I didnt figure much of it, but also didnt figure it to be considered normal. I did some reading tonight ( thanks s2000nvegas ) he had a ton of good info about the flicker in my dash. I already ordered new coils and bkr8eix-11 plugs but I have a feeling that maybe low voltage is my issue.

Thinking that maybe the cause of the missfire was the weak ignition because of an alternator that is going out. I am also going to go over all my grounds and make sure they are all clean. Dont know if any of you other guys ever see the dash flicker but if you do...get a new alternator.

Oh...also...I have a small odyssey battery too...poor thing might be killed after this. Ill have to test it, never fails to start the car so Im hoping for the best.

yea mine does it more at idle but at cruise you can still faintly see it. It makes me wonder...so Im gonna replace the alternator today and see what that gets me. Assuming someone in town has one for my car. haha
