I have a 1988 Pontiac GTA Trans Am was driving it tonight everything was fine and has been fine, I stopped in front of my house for about 2 mins left it running and it stalled, started right back up but the idle was kinda up and down.

Took it around the block and then went to put it in my garage, put it in park got out and opened the garage and it stalled again, started right back up and I hurried up and put it away.

Anyone have and ideas or have a problem similar to what it could be. Thanks
