Triton V10 dies while slowing down for a sharp turn

[1ramblingman]

Getting ready to sell our 2006 8295 and upgrade. F53 chassis, Triton V10. 43k miles on it. Have an issue that needs addressed first and wondering if anyone else has had this problem and what resolved it. When slowing down to make a sharp turn, like into a parking lot, the engine will drop to about 500 rpm and then die. Always starts right back up, runs smooth as silk but it's kinda scary when you lose your power brakes and steering. I haven't found any "known" issues, no codes being thrown and other than this issue, it runs perfectly. I did read one article about performing an "Idle relearn" but that would have to be done every time the coach battery disconnect switch is used from the way the article read. This doesn't happen very often but looking to get this resolved so we can sell it and make sure the new owners are protected. Any input is greatly appreciated and thanks for taking the time.

You may want to ask the admins to move this thread over to the Ford chassis section. There are some very knowledgeable people over there. Maybe they will see this though.

It was asked here, w/o an answer, so do you, if so, what model?
There was a recall on some BCC models to bypass the chassis battery as it could cut power to the engine, just want to rule out that possibility.

It sounds like the power brake hydro boost doesn't like braking and steering at the same time under low speed.

My 2007 8295 has done that a couple times. I haven’t figured out why. It is scary when it happens though, no power steering nor power brakes!

On my other vehicles that was the idle air control valve. It’s located on the throttle body. Not sure if the same on a V10 but worth investigating.

I thought I had updated this but clearly I haven't and do appologize. What solved the problem of the engine dying was cleaning the throttle body. It didn't look that dirty but after an hour and a half to two hours of removal, cleaning and install, the problem was resolved! It is absolutely scary stuff to lose your steering and brakes with 20k pounds of momentum going!
