Engines surges at idle

I have a 1994 Isuzu Amigo. When I first start the car it runs perfect but when it reaches operating temperature it surges at idle. If the engines comes just above idle it does not. The surge is so even it is like a pulse, surging about every 2 seconds. I'm not sure of the engine size but there was only one inline 4 cylinder engine offered. This vehicle is a stick shift. Thanks, Sharring

Two things will cause an engine surge 1. Low battery or bad alternator. "Check battery water, if low fill and charge battery by running or hook to charger" if surge doesnt stop within 10 minutes or so, have alternator checked.
2. Low compression or blown head gasket.
Hope this helps
