Check to make sure the upstream 02's arent majorly fugged up , one or both. When I went on a test drive with them disconnected, it would hover at 500 rpms, sometimes fluctuate then just die in neutral, coming to a stop. It didnt do this all the time but alot. Stop doing it when I reconnected the O2's, after the test - and had the codes cleared with a scanner. Also, I know that a MAF not reading the correct airflow, for example when the center post's backplane is removed, it just dies BAM in neutral or coming to a stop. Now I have a 5-speed but its still a v6 Contour. For what its worth. Cheers
