Hello,
I know this is mainly trucks but this could be a problem that someone else has seen. I have the 4.6 Triton V8 and it has 58K miles on it and you can be driving along and let off the gas to start braking and the Van dies. It always starts right back up and will not do this consistantly. It is driving me nuts, any ideas?

We had this same sort of problem with our van awhile ago, except the van died during right hand turns. It turns out that all that was needed was for the throttle body to be cleaned well. Hope this helps.

Well the problem is fixed! I tried a combination of two things, disconnected the battery for an hour to reset the electronics and changed the fuel filter.

I don't know which one worked but momma is happy, Thanks for responding Marshall.

Glad you were able to fix it relatively easy covering the basics first.

Well, it looks like I spoke too soon, it happened on me twice last night. I still think it is some kind of fuel problem, because when it happens the RPM's drop off like the car is running out of gas, instead of a sudden ignition kill.
There is a fuel pressure regulator I saw in my manual that says it controls fuel based on the engines vacuum, but don't know if that is it or not. Or should I break down and have it checked for failure codes?

That's where I'd go,Clark. The codes will eliminate alot of sources for problems.

You probably have a vacuum leak-- It's common on thoe trucks. Check the PCV valve grommet on the back of the intake manifold. Especially if it is a 1997. The 90 degree grommet likes to melt there. Also check for leaks in the intake hose after the mass air sensor (its inside the air filter housing)

Is the check engine light on, ever? If not then there is no reason for checking the codes. If it comes on sometimes but goes away its probably a lean code, common when vacuum leaks are present. It means the computer has gone full rich but the O2 sensors are still reading lean.

Thanks for the input,
Cp the check engine light never comes on so I will start looking into a vacuum leak.

I also am looking at this fuel pressure regulator that runs off engine vacuum to maintain steady fuel pressure. The funny thing is that I called the local Ford dealer to check the price and they told me that they were out, sounds like a possible high use item to me.

Ask the parts guys if they normally stock it, they usually know what is a common problem. If you take the vacuum line off and gas comes out, the diaphram is ruptured. If not, it is probably not the problem.

Make sure you pop off the engine cover and check the intake end of the PCV hose. It should be on the back of the intake but on a van it may be on the back of the throttle body elbow. I've changed 3 at work and they were all 1997 trucks (2 F150s, one Expedition)

Clark, since it does this when you start to brake, check for a vacuum leak in your brake booster when the pedal is depressed. Get up under the dash with the engine idleing, press the brake pedal, and listen for a leak.

If it has a booster check valve, look at it also.
