I have a 2002 Chevy Trailblazer 4.2 L6.
The engine turns over, but sometimes the headlights dim for a few seconds before the engine idle increases and stabilizes.
My car horn is sometimes very quiet if I set the alarm after turning the engine off.
A few days ago, the engine repeatedly stalled out right after starting it up. It took over a dozen key turns to get it to stay running!
I recently replaced the #3 ignition coil, so I wondered if I damaged a nearby component during that repair.
These symptoms appeared after the repair.
I have attached a screenshot of my latest Blue Driver scan report.
Do any of the codes point to a cause for the intermittent stalling, dimming lights, and quiet horn?
If not, do you have any suggestions for diagnosing the issue?
TIA for your help!
