Keith -- I just fixed the slow shut off issue with the '96!!

Last fill up I dumped in half a bottle of DieselKleen. All the sudden she's shutting off properly with no CEL.

??!!!!???

Could some issues with these first generation all electronic diesels be related to ultra low sulfur fuel?

Wow great news Bill I would never have thought with a new fuel shutoff valve contamination would have been that quick of an impact.

all of the liturature I have been given since the introduction of ULSD states it should not but anythings possible glad to hear you did not have to spend big bucks to get that solved.

Maybe contamination, maybe the way USLD affects o-rings? Who knows? All I know is it's working right now.

Wonder if your ignition switch is going bad? The 80c thing would suggest not, but now it's doing it at all temps.

Go crank the car and jiggle the switch while it's running and see what happens.

Just a thought.

I did have the same thought about the ignition switch I have a little time today I will try some wiggle testing there and other areas. Take care and thanks for the ideas.
