Sorry So Late,
I Own A 98 Cl 3.0 And Came Across The Same Problem. Infact After A While The Stuttering Leads To The Car Actually Dying Out Completely And Its Hard To Start Back Up.
I Took It Into My Local Acura Dealership And Found Out That It Was Due To A Recall On The Egnition Switch. They Paid For Everything
Look It Up And Save A Whole Lottah Money
