So I have this issue that seems to come and go.. it’s hard to explain but basically one minute the power is there car pulls like a train next minute it seems like half as powerful.. it baffles me it will run perfect for first 10-15 minutes then it’s like half power.. if I restart the engine it seems like it’s a full power again then 10mins later back at half power..

I don’t know if it’s limp mode or maf sensor I’ve been told it could be a lot of things.
I have few codes 17705 I’ve recently replaced DV for a forge 007p.. also got a 02 sensor code due to decat but that’s it..

Its like one minute it’s at full power the next it’s just gone ***..

Specs : 1.8t AUM, Forge Tip, 3”decat, Forge 007p, n249 bypass. Stage 1 remap
Everything else is standard.
