What To Check
The core symptom (reduced/low power, MIL illuminated) is genuinely detectable on a normal test drive and cold start. Which of this card's several real candidate causes is actually responsible is NOT distinguishable on a test drive alone - it requires a scan tool read of the actual stored code plus the physical inspection sequence in this card's own diagnosis steps.
