One of my vans is cutting power after it sits at idle for a few seconds. It doesn't do it during a load, but it runs fine through traffic and when you come to a stoplight and sit for 30sec or so and get back on the gas, it is gutless.. I also hear a different tone in the exhaust when this happens. Like some kind of bypass for the turbo opens.. We open the hood and brake boost the van and try to listen to any boost leaks, we can not detect any leaks in the resonator or any hoses we can actually see. It is driving me and my employees crazy. Any help would be great!
