I I I took my 1997 To I took my 1997 TOYOTA Corolla to get it smog and this Is the first time it failed idle speed to high 1400 rpm said I need to take it and have it turn down to 700rpm


Idle speed on most later model cars is automatically controlled by the on-board computer. If the idle is too fast, it is usually due to an intake leak somewhere on the engine, or a malfunctioning sensor. Either can cause this result. There is no "adjustment" to be done, but once the source of the problem that is resulting in the fast idle is corrected, it should return to normal.

I have a1995 GEO prism it runs good but when I let off of the throttle it won't idle unless I keep my foot on the throttle


Clean the throttle body and idle air control motor. Just a cheap start. Could be the engine is old and tired.

'03 Toyota Corolla 1,4 VVT-i 4ZZ engine idle rpm


Idle is factory set and cannot be adjusted, your best bet is checking for cracked hose pipework for air intake at idle,(not at problem under exceleration and driving) Any slight upset to the air /fuel ratio will be most prevelent at idle speeds.Check hoses where the meet metal flanges on manifold intakes and any sharp bends in ppipes.Good luck
