I am the original owner of a 1990 Toyota Camry,4cl, 5 speed manual with 180000 miles. The engine races like crazy in neutral. When I am in second gear and let out the clutch the car will travel 10 miles an hour without stepping on the gas peddle. A little scary! Any ideas?
There are many things that can cause this fast idle condition.
Make sure there are no air/vacuum hoses disconnected.
There may be a problem with the Idle Air Control circuit. There’s a component on the throttle body called an Idle Air Control/Air By-Pass motor. If this component goes to the wrong position for the idle condition, it can cause a fast idle.
