I have a 1991 GEO Prizm GSI with the 4AGE motor 101,000 miles on it. It is great shape and has always been taken care of. It runs amazing except for one problem. When you shut the car off after complete warm up and shut it off ( like to run in the store for 10 minutes ) and go to restart it dies. It is like it will not idle I have to give it gas. Before shutting it off and all other times it idles fine. The car is a manual.
