Hello all, dealing with an 01 740, wen I start it, idle is at 900-1000. when warm, goes up at 1300. New maf, no vacuum leaks that I have been able to find. I am wondering if this could be one of the engine temp sensors. Anybody have any clue?

Was the MAF an OEM version from BMW - or a Chinese copy?
