What’s funny is, it’ll take me months to diagnose this if not longer with winter coming up.
I’m printing this information with checklists and making a folder. Obviously I just ordered an OEM filter, back to basics...like your house...never use fancy filters ALWAYS use cheap high flow filters and change often...(I didn’t think about that so thanks Gunkk fir that reminder, made me feel stupid...if the shoe fits right)
...off we go.
