Got a rrfpr fitted to my car and was all setup for correct afr but today whilst under the bonnet I checked the nut at the top and it was loose. There is a normal nut close to the body of the rrfpr and a kinda rounded style one on the top of that (which was the loose one) I think this is just the locking one? So i just tightened it down to the normal nut to stop it moving. Will it be ok or will I need to get it checked as I don't think there are any garages near me that check afr's.
