Alright I’m bringing this back up because my car is still having some issues. After fixing my header leak I thought the car was running fine because my AFR finally started acting normal. I sent a log to Brandon at Lund and he told me the car still had some issues so I started looking and I...

Alright guys im back. I thought I fixed the problem but Lund is telling me I still have some issues after my last data log.
