I have a 1994 E150 conversion with a 351W engine (best van I've ever owned). Now approaching 200,000 miles it has developed two problems that the Ford dealers haven't been able to fix.

(1) The engine cuts out and right back on -- like turning the key off and on only much faster than you could possibly do it. This happens several times a minute regardless of whether you are idling, accelerating, or just cruising.

(2) At times it seems that the throttle sticks. Seems OK until you take your foot off the gas and the engine won't slow down. This problem comes and goes.

Two different Ford dealers have tried to fix it, and both gave up -- saying that they no longer have a diagnostic computer that will work with this vintage vehicle.

What do you suggest?

Guess the dealer techs are at a loss without parts on the shelf LOL.

Since this is going to be tough to nail down, you can try to determine if it is losing fuel or spark by hooking up equipment and monitor it.

IF you tend you have a wad of keys, then I would suspect an ignition switch. You can try to wiggle or tap it or remove the wad of keys to see if you can find a pattern.

Throttle sticking may be a carbon clogged throttle plate, bad cable or mechanism or possibly a carpet wedged under the pedal.

Thanks for the negative points.

2 dealers can't figure it out with the van in there presence. So you go to the internet and expect a miricle?

I give you ideas on how to go about diagnosing and you were expected a magic bullet instead? WTF?

How about engaging in a dialog to gain ground? No you have to be an ass and whine instead.
Take it back to the dealer and make their life miserable.

I would suspect the fuel injectors are not working right. Check the fuel regulator to the injectors that tells the injectors when to shoot in the fuel mix the rely for that and the ignition switch
