I am at my wits end! My 2001 2.4T V70 hunts at idle between 400-900 RPM and typically stalls. This happens regularly comming down from a highway cruise which can be a big problem if it stalls when I am still in forward motion (brakes and steering). It will also start to hunt and then stall at stop lights. It has been at the dealer for a total of 12 days this month and they have replaced the Mass airflow sensor, the ECM, turbo intake tube and pressurized the intake to check for leaks and performed an exorcism. The problem still exists!! Anyone out there have any insight to this problem? Anybody having same symptoms? HELP?

Anyone look at, replace what's called the battery B+ cable that goes from the battery and supplies voltage to the engine area fuse box? There's a TSB on it. If it's NG, it looks discolored where it attaches in the fusebox and that'll cause the problems you're having. Otherwise, they should be working with Volvos tech support people.

They have been working with the Volvo tech rep for a while now...they have not mentioned the B+ cable yet. I will mention it to them and do you know the TSB number by chance?

Thanks!
