Jumpy needle November 15, 2006, 06:41:59 PM Well, I've noticed that when I'm driving, my tach needle jumps up every couple seconds. It only started doing this when I unhooked my MSD 6a box. The box was sucking power, so my car wouldnt start. I did pull a spark plug to do a test, and i think that is what might be acting up. I havent had the time to check it. Any ideas?It's a stock 5.0.
