So I've got a 2015 with 118k miles on it. Haven't done any of the suspension or motor mounts and now I have surging when in reverse or idle and the AC is on. CEL throws a code for lean bank 1 and no others. I've been told the PMM is to blame and regardless needs to be replaced. I figured if I'm going to go for that than I might as well get the others. Wondering if anyone has any recommendations on tried and true motor mounts. I don't care about vibration or ride quality. If it's poly/solid rubber/hydraulic just need some suggestions. I've noticed most have G1/G2 Mazda5s so any help is greatly appreciated.
