This Commodore came in running rough only when cold.
We found this injector had extremely high resistance when cold and rectified itself once it warmed up.
On the bench with a multimeter connected, we checked the resistance when cold, and then applied a heat gun to it to watch the resistance come down to normal.
Nothing like proof to confirm a repair!
