I have an 01 Cl-s auto...Love the car but lately it would on occasion at startup after driving around spudder and stall. Does it a few times and starts right up. Today i went to start it up for the first time in the morning without driving it and it did the same. But this time instead of starting up it just cranks over and over. The check engine light is Not on. Did a search and read some posts about iac valve and something to do with a fuse that controls the fuel pump...Any ideas guys?
