While I don’t know how helpful these suggestions will be, you can try them.

Intake air (vacuum) leak  
Faulty fuel pump  
Faulty Idle Air Control system  
Faulty emissions systems

[b]When the surging happens, and if you’re in gear, firmly step on the brake pedal, and slightly step on the accelerator. If the surging stops, suspect the idle air control circuit or a vacuum leak as suggested.
