:banghead: Does anyone have the same problem as me. I had Map sensor codes so I replaced it with an ac delco. The codes have been cleared and I disconnected the battery to clear as well. I do have some residual oil in the intake which I have read is normal but the p071 code still returns does this indicate a faulty second sensor again or is this a normal intermittent problem . The good side is the car still runs smooth Any suggestions???:bonkers:
