Why does my 1991 Subaru Legacy's RPMs surge from 500-1500 when it started today?
Mine was doing that for a while. I took the Idle Air Control valve apart and cleaned it. Problem solved. Its normal for the engine to idle higher when its cold though. Once it warms up a bit the idle should settle down.
Idle surge problem while in neutral rpm goes up and down?
The idle surge problem, where the RPM fluctuates while in neutral, is typically caused by issues with the engine's air-fuel mixture, a malfunctioning idle air control valve, or vacuum leaks. It can also stem from dirty throttle bodies or a failing mass airflow sensor. Diagnosing the exact cause often requires checking for error codes, inspecting vacuum hoses, and cleaning or replacing affected components. Addressing these issues can stabilize the idle and prevent RPM fluctuations.

What would cause power surge in a 91 ford escort?
A power surge under a load is probably the transmission slipping. If its a manual transmission the pressure plate is slipping on the disc. If it is an automatic most likely it is a worn clutch pack slipping. If it surges at idle with the tranny in park the surge is usually a defective IAC (Idle Air Control) valve.

most common problem causing a surge while a car idles is the MAF-Mass Air Flow sensor is contaminated. typically this will throw a code (check engine light aka MIL)
