I have a 97 E420 that is stalling at a stop when the temp gauge gets around 80-100. I have changed the KPS and it's still doing it. It doesn't take a cool down period, it starts back immediately, and I don't have any CEL, but when it stalls the ARS and battery lights come on. I've read also that it could be the MAF, but again, there's no codes. Any help would be appreciated. Thanks in advance.
