Hope I'm not too late. Dude I'm booked this weekend man. I got a gear install with a buddy planned and I need to align my car due a geometry change made last weekend. Then on sunday I need to clean up my damn house cuz my wife's coming home for a visit

and me house is thrashed!
If you want you can come down saturday and I'll take a few mins and we can check it out if you like. I'll be able to tell if it's in open or closed loop right there in tha parkin lot. I can't really commit to alot of time with it though dude. I've told this dude I'd help him already. What did you want to diagnose? just whether it's stayin in clsd loop? you got a check engine light on ?
