Ignition spark generation and cylinder combustion health on the 2023 Chevrolet Blazer V6 engine are managed by individual ignition coil packs, threaded cylinder heads, and iridium spark plug electrodes.
How to Fix It:
-
Remove Coil Packs: Unplug the electrical connectors and unscrew the individual ignition coil packs mounted directly above each cylinder on the V6 engine.
-
Extract Spark Plugs: Use a ratchet with a spark plug socket and extension to carefully unscrew and lift each spark plug out of the cylinder head.
-
Inspect Electrode Condition: Check the plug tips for heavy carbon fouling, excessive gap wear, or oil contamination before reinstalling or replacing them.
