Running on 3 cylinders

[madman23]

The title says it. My car started to run crazy as I went onto the highway. It was boggin, backfiring, rough idle. Checked my vaccuum lines, swapped my ecu, changedthe distriputer cap and plugs because I found that 2,4, and 6 are not getting any spark. Whats going on with me baby?

Check the wiring harness to the injectors , i was reading another thread on the forums about this..... i believe the plug is supposed to be "under" the intake manifold somewhere and can be a good source for moisture and corrosion to form.
