I have a 2006 V70 2.5 T that has recently started to intermittently idle rough and stall. I can go for a day without a problem the next day start up again. Sometimes when first started or after running for a while, it seems to have no rhyme or reason. It shows two codes, 1010 MAF out of range, and 1070( I think) fuel trim bank one. The MAF is a new bosch unit. I have looked for vacuum leaks but no luck yet. I wondered about the A/C idle up as it seemed to smooth out when I turned off the A/C this afternoon when it started to idle rough. Since it is inconsistent this might not have meant anything.
