2004 bonneville sle 0300 code 4th coil no spark
When driving it you need to give it more gas, idle is really ruff. Code comes up 0300. Replaced plugs for iridium gap 060, replaced wires. Tested coil. No spark on #4. Idle seems low and stalled once at stop.

Sounds like a bad coil but you can always swap them and see if the problem follows.

Did replace the coil. Next step suggested is the Ignition control module. Is there a way to test the ICM before spending 200.00?
