My 93' Caprice Classic Stars And Runs But When I Drive And Stop At A Light Or Stop Sign It Cuts Off. Once I Put It In Park I Can Cut It Back On With No Problem. It Doesnt Make Any Wierd Noises, Its Not Leaking Antything, So I Dont Understand What The Problem May Be. Can Someone Please Try And Troubleshoot My Issue With The Information I Provided?
Try cleaning the throttle plate on both sides with choke cleaner. Oil gets in there and makes it gummy and gives a problem like yours. Tis is the easiest to do first. If it still does it then it needs to be checked in further.
