Question about 1989 Toyota Camry

1989 toyota corolla rpm goes down than up

When stoped the rpm sometimes goes down to about 500rpms than will rev way high. This doesn,t happen all of the time. Seems like when you start it it doesn't want to idle.

First thing to look for would be vacuum leaks. Make sure all your hoses are good and tight, and no cracks. With the engine running, wiggle them around and listen for a hissing. Then check all your intake bolts for tightness. You may have a leaking EGR valve, or a plugged PCV. Make sure your air filter is clean. Try those for a start, and let me know. Good luck.

'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

My air condition works but when i turn it on my rpm goes down y is that ???????


The air con draws a small amount of power from the motor.When its turned on,the revs will drop.If the car is an auto,there is an up idle switch/sensor attached.What it is meant to do is bring the revs up just a small amount to compensate for the air/con.Manual cars have the same thing but set up just a little bit different.If the car stalls,get the idle up switch checked or adjusted and all should be ok.Hope this helps you
