Your problem with the Olds diesel was probably due to a misadjusted or bad fuel pump. In that pump the throttle pedal moves a fuel governor assembly which in turn controls a fuel metering valve. In effect the driver is not directly controlling injected fuel quantity. If the governor or metering valve were not spec'd and adjusted correctly you could have some very abrupt speed/power changes.

That sounds reasonable. Sounds like mechanic is one of your trades. How much do you know about Ford 300 6's?

Being a mechanic is sort of a family tradition as well as a skill of necessity for me rather than a trade. Over the past eight years I've developed a pretty good knowledge of how diesel FIE works. Of that particular Ford engine I know nothing. All IC engines are the basically the same though. If you want my $.02 on a problem freepmail me. I love distractions.
