Experiencing an occasional hard-start/won't idle problem in my 2000 Deville (117k miles). during these instances, it is necessary to drive with 'both feet'. Sticky throttle cable? don't know if a code has been written

 

Did you ever figuire out your problem? I am having similar problems.

 

replace both crank sensors

 

Cleared problem by replacing both crank sensors. Pricey, and hard to get to, but problem is gone.
