My '95 GT sometimes has a sudden surge in RPM, and you can feel and hear the engine surge. The surge stops on its own. Sometimes it happens 2 or 3 times in a row an sometimes it happens once. It mostly happens at 50 -65 MPH. It happens maybe once every 3 or 4 weeks. I use Tectron fuel system cleaner every couple of months. Any ideas about what could be causing the surges?
The first time it happened the car surged, and I thought it might be the transmission (AT), but had the trans thoroughly checked and it was fine. Thanks.

Maybe your IAC is going bad or dirty or could be something else. That's the first thing I'd try. I am working on my 94 right now witha surging issue. There is also a thread on it here at stangnet. Search for surge or surging.

Sudden Surge

After some checking with mechanics, it is looking like it might be torque converter problem. Seeing transmission guy next week. No touble codes stored.
