The crank sensor appears to have resolved the cold start issue; no rough starts in the last couple of days. However, the vibration in the steering wheel remains while the car idles. I'll update the original post as we sort through the vibration issue.

Hey John, if the vibration @ idle in the steering wheel ( presumably in "D" ) disappears in reverse, the engine mounts are no good. Try it out.

The vibration is in all gears. Anway, the motor mounts and transmission mount were already replaced.
