Firing Problem
So when i turn my 280zx on it runs ok but there is a misfire problem when i put my foot down on the accelerator. Its running lumpy and i just replaced all 6 fuel injectors so im not really sure whats going on so any help would be great thanks.

Timing?
Spark?
Fuel?
AFM / CHTS & connections?

Did it run fine before you touched it?

It ran ok but still had a misfire so i thought that changing the sparks and the fuel injectors would do fix it but its still got the misfire when i accelerate

a misfire under load is commonly a problem in the secondary ignition system.. check all those components
