I didn't think a fuel delivery problem was affecting the IMS.

I don't know the specifics, but recall reading that the Intermediate shaft is under the most stress at lower RPMs, in lower gear. Supposedly why failures seem to happen at low speed, e.g. accelerating away from a stop light (as in our case). If this is true, I wondered if there was enough resistance at this point to cause the engine to hesitate.

From subsequent posts, it sounds like experts think this would not occur. If so, the hesitation probably was a fuel delivery problem, and not related the IMS problem. I just found it odd that it only happened in a certain RPM range in 2nd gear.
