My AFRs are seemingly high on my 03 cobra. At idle it sits around 14.5-15.0 when cold but once it warms up it nears the 16.0 range. After driving it a bit it will climb upwards of 16.5-17.0. I'm leaning toward it being an EGR issue as I can hear it leak once car is warm. Am I right for thinking this leak would cause the motor to run so lean? Could it be the tune? Or combination of both?
