Update: Our mechanic isn't one of those guys who replaces parts to just replace parts but since the diagnostics repeatedly showed an error with the crankshaft position sensor, he replaced it. Of course, that didn't take care of the problem...although things seem a little better. When it stumbles and surges it only does it for a second or two then smooths out rather than carrying on for several minutes.

So any further advise would be greatly appreciated. My husband questions the injectors because it only happens the first trip of the day. He thinks that if it were related to injectors that it would happen at other times as well. Any feedback? Any of you techs have any ideas? There aren't a lot of the 400E around our area and so the mechanic hasn't ever experienced this model with these symtoms (except when the wiring harness hadn't been replaced). Of course, this raises a question...we were under the impression that once the harness was replaced that it would never be an issue again because of the improvements to the new harness. We had it replaced about 4 years ago. Might it need to be replaced again?
