My Jakes and my mph gauge started to act up. Gauge needle only works when going above 25 mph and Jakes cutting out by it self and lowering banks by itself. I find it sketchy that these things started to happen all at once. Any idea what I need to check? I’m thinking something electrical or computer? Thanks

maybe turbo arm starting to hang up?

Update: this was causes by bad spedometer sensor. It also causes cruise control to disenage and eld device will malfunction too because it’s not reading mph properly. Mine was rotted inside.
