5T4R7ET N/A Posted March 23, 2011 Share Posted March 23, 2011 well when the car is fully warmed up the air/fuel ratio should be 14.7 on idle.when accelerating this will change, depending on if your on/off boost.cold start = 12.8:1 - 13.5:1acceleration = 11.6 - 12.3:1 deceleration = 16.2:1 - 17.6:1light acceleration = 13.7:1 - 15.2:1hope that helps Quote Link to post Share on other sites
