So after bending some valves and putting on a new head MLS HG, ARP studs 248/232 cams etc, I start my KA and it has a very minor misfire at idle. I took a timing light and put it on each cylinder to find that all the cylinders would occasionally misfire and none more than any other.
I have newish wires, brand new plugs and brand new cap and rotor. still no change. So now im kinda at a loss for what to do next. The I opened the IACV up a little so it would stall when stopping at a light but its will still bog down to 650 and bounce around but once you hit the gas and its above 1000 rpm it doesnt feel like ive lost any power.
Because I could see the misfire in the wires im assuming its an Ignition problem but before I start tearing things apart I wanna get some opinions. Maybe my dizzy is bad? Its just weird how it started right after the head swap.
