I have a 1996 Grand Am 2.4L. I have an issue where it feels like it's about to stall out but never does. Sometimes its only for a split second some times lasts a few seconds. The quick ones feel more like a throttle response issue but the long ones feel like its going to stall. The fuel line seems fine (new filter as well) and the air way seems fine. It might be electrical I'm thinking. It also has an issue with the speedometer. I don't know if they are related. The speedometer works sometimes and sometimes not. If its not working it'll go up to about 20 mph then drop to 0 and usually wont work for the remainder of the trip. But if i stop and go it'll respondand go up to 20mph again and drop. Some days i can do highway speeds and the speedometer works fine. I have replaced the speed sensor. The car isn't showing any codes at all.
