1990 240sx misfire!!

[darknessturbo]

I need help finding the cause of my misfire. I have new wires, plugs, fuel injectors. Its happens when I give it about 20% throttle

check your fuel pressure, vacuum to fpr, and more importantly, your timing and advance. start with that. Right plugs? right injectors?

a lot of time when i replace plugs wire and cap and rotor i forget to mark the order and i flip flop a wire and get a two cylinder misfire. make sure it on the right way.
