I have 1997 540i - 174000 miles well cared for with no current issues. I was driving along and all of a sudden it started to run horribly. It had no power and would not idle under 2500 rpm. Code 73 pops up on the Peake. Are these the symptoms of a bad MAF? Is there any way to check the function of the MAF with a volt meter?
Thanks
