I was getting the P0021 with Cobb's Stage 1, Stage 2 and now got the same thing with PDX's custom map. So seeing PhilT's misadventures and his datalogging, I decided to do the same thing. So here a run little run in which I get quite a difference between the OCV duty left and right.
Am I due for new OCVs? If the car is still under warranty you think I could get them for free? (Don't know how to explain to the dealer how I knew it was the OCVs that were defective though! without telling him about the AP).
If the dealer option is a no-no, can I order online or I still have to buy from the dealer?
