Help! Stalls Out.

Hi guys,

I'm new to the forum, so maybe you've already answered this somewhere, but I've got a 1990 Ford F-350 with a 7.3 ltr diesel that stalls if I lift my foot rapidly from the accelerator. It will restart easily, and it doesn't make any funny noises, it just dies. It will idle, you just have to lift your foot slowly enough so that it doesn't die. I've had it recently serviced, new fuel filter, no obvious fuel or air leaks. Does anyone know what might be causing this?

thanks

Has something to do with a little valve on the fuel pump (I think) that needs lubrication
It's a metering (spool) valve that can hang up. If the problem returns, it's probably scored but can be replaced and its bore smoothed but that requires a IP overhaul. Besides a lube, ATF has a very powerful detergency additive. Even works on humans, We used to overhaul lots of heavy truck Allison automatics and no matter how dirty our hands were, when tearing the trans down and wading around in the ATF a while they'd soon be clean as a brain surgeon's.:icon_wink:
Now that was a good one!:lol::lol:
