Most common problems, symptoms & fixes for the G4LG engine.

Engine G4LG is known for reliability but can face common issues like carbon buildup in intake valves, rough idling, and occasional misfires. Diagnosis involves checking for error codes via OBD-II scanner, inspecting spark plugs, and performing a compression test.
