Still have the problem? Possible vacuum issue
Problem gone? ABS is causing your problems.

Simple..

Bye, Arno.
Arno,

You're correct this is a good approach and we ran the car like this for a while. The ICE mode issue went away in exchange for early lockup of the fronts due to brake bias. However, when reconnected the "ice-mode" reappears. Our supposition is that the lack of brake boost impacts the system less when the ABS isn't trying to pump the brakes repeatedly. Once we fit the vacuum canister, the problem went away permanently regardless of ABS or not.

'soup,

The check valve is a connection between the vacuum hose that runs off of the intake manifold/throttle body. Follow the hose to a fitting that connects to another hose. The check valve is two barbs, one on either side of quarter-sized circle.
