Subaru XV Crosstrek loss of acceleration and pedal response related to alternator replacement on Subaru XV Crosstrek

Some Subaru XV Crosstrek owners report experiencing loss of acceleration and pedal response after an alternator replacement. This issue may be linked to a dirty throttle body, which can result in slow acceleration. Additionally, improper or damaged wiring between the battery and alternator can lead to significant performance problems. Some owners also find that hesitation or power loss during acceleration can stem from contaminated gasoline or other fuel-related issues. Furthermore, complications with the EFI system, including malfunctioning fuel injectors, intake valve deposits, throttle or pedal sensors, and spark plugs, can adversely affect acceleration and pedal response. It is recommended that owners check the throttle body, inspect the battery-alternator wiring, assess fuel quality, and evaluate EFI system components to address these concerns effectively.
