Braked hard for an ambulance. Went into limp mode and all the codes lit up. After about 5 minutes it ran fine but still had the codes showing then after I stopped and started again, it slowed back down to 30 mph. I've seen a few posts about this but none of them mentioned it ran fine after a few mins then went back to limping. Can anyone point me to a part that might be broken or disconnected?
