Engine shutting off on decleration
I have an 05 ex with about 120,000 miles on it. Has always ran great. Recently, it started shutting off on deceleration. Doesn't wind down or anything, just shuts off, does it most of the time so it's a real pain to drive. Took it to a local mechanic and it continues to shut off but it isn't throwing any kind of code. They've went through everything they can think of - anyone have any experience with anything like this?
I use my truck everyday and so does my daughter. It's become a safety thing now because if we had to panic stop, I don't think we could when it shuts off.
Help?

If it is a gas v10 or v8 it is probably your idle air control valve. It will not throw any codes when it is out. You can take it out and clean it successfully, as I had to this summer. Took me a whole 45 min start to finish. It is located behind throttle body.

I had the same thing happen to me once....the garage kept replacing fuel pumps and fuel pump relays and it would do the same thing after a couple of weeks.Turned out to be the wiring harness for the fuel pump from the relay...when the truck was sitting still or on the gas, it checked out ok. It was a wire corroded on the inside of the insulation. When you would let off the gas, the body would flex enough to disrupt the power and the fuel pump would shut off.

This would be my first guess.

I've had the same problem with my '05 6.0L. It will happen a few times in a row and then will be fine for awhile (weeks at a time) and then start up again. I am puzzled. Would you mine sharing the easy fix?

I don't think we know yet which engine we're discussing. Hopefully SuzukiMom will get back to us.
Found a video, for a mustang, but the same idea. For the V10 Ex it's all under the windshield and a PITA to get to.

Lots of other video's to watch related to this one.

You might want to have it checked, dont let it go too long like I did.

Mine only happened on deceleration, the engine would just die. No codes. The last thing the mechanic did was to clean the EGR again. When he looked inside the EGR port there was quite a bit of carbon. Apparently the EGR was hanging open just enough to stall once in a while. It didn't happen all the time. Cleaned that out and I have not had an issue in almost 40k.
