SUMMARY
Replacing a car battery can lead to temporary stalling issues due to the Engine Control Unit (ECU) needing to relearn fuel-air-timing settings. This phenomenon typically occurs in modern fuel-injected vehicles and may resolve itself after a few days of idling. The ECU adjusts various inputs to optimize engine performance, which can explain why stalling may happen initially but not persist. The discussion highlights the variability in vehicle responses post-battery replacement, emphasizing the importance of knowing the specific make, model, and year for accurate diagnostics.
