Hi guys I'm new to the Honda world but have been in a GM dealership for two years. Anyways, I have a stock d16y7 with unknown miles. I have a awful random misfire on acceleration and a couple cylinder misfire codes popped up on my snap on scanner but I've replaced all I can think of. I have a new dizzy, plugs, wires, O2 sensor, crank angle sensor, my injectors are pulsating I believe, got data on my map sensor. Just lost at what it could be. I've changed the dizzy twice already and plugs. also, the speedo doesn't work.
