I picked up my versus and copy of danners book and trying to get into it with my own vehicle that has a rough idle(shake that looks kind of like a misfire) it runs great at any other speed and I can’t really say that it has trouble taking off from a stop either. I have a picture of the waveform and when snapping the throttle it seams cylinder 8 jumps way up on the kv scale above any other cylinder. I attached a picture and need some help figuring out what all this means.
