Default Have a stuttering issue at 7PSI Presure tested and found nothing.
So far no codes, but I do get Cat efficiency codes occasionally. I tried driving without the MAF and that made no difference, I logged the coolant temp sensor and it looked correct.

I'm thinking that this is either a BPV or the N75. Does anyone have any other ideas what I should be looking at before I start replacing these valves?


Thanks!
