I have a 1990 Supercoupe and have a problem where I will drive the car awhile and it get up to operating temp and it seems to be during the spring and summer season while driving around town with alot of stop and go. I will then shut off the car and go to a store. This is where the problem starts. I then come out and start the car and it idels rough and then stalls out and it keeps doing it. If I keep my foot on the gas pedel and get the car moving it straightens itself out. A few years ago when I took it into the dealer for them to look at it, they said it was the throttle body. They said they cleaned it and that it should run fine. Once again I am having the same problem. Any suggestions would be great.
