From VFAQ.com:
"Q: So what, exactly, is idle surge?
A: Idle surge is the condition that occurs when something in the ECU idle speed feedback loop fails to operate as expected. Since the ECU is not quite as smart as you are and has a very microscopic view of its world, its behavior may seem very strange to you, but seem perfectly normal to the computer. The result is an idle speed that oscillates from ~1200-1500 RPM about 2 times a second and no error codes are ever displayed."
Does this mean if an engine oscilates from real low RPMs to high RPMs (around 500- 1400) that the problem is NOT idle surge?
