The fast idle on my 98 Camry LE doesn't kick in right away when I start it. After a minute or two it does, but until then it cold idles at about 400-500 rpm. The coolant temp and intake air temp sensors checked out ok according to the tests recommended in my Haynes manual. Any suggestions?

You are not stupd! :-) This car has a speed-density system. The computer is programmed to meter fuel and spark timing from manifold absolute pressure (MAP), engine temperature, air temperature, and throttle position only.

Are you having a problem?

Hello

I just worked on this problem a couple of days ago. If the motor is a 3.0 liter. The idle control valve is located at the bottom of the throttlebody assembly right below the bore for the throttle butterflies..What usually causes this valve to go bad is the mechanical part of the sensor sticks as it becomes sludged or carboned up. Manufacturer claims that the valve cannot be cleaned and should only be replaced....It's a high dollar repair to replace this sensor as your engine coolant flows through this electrical valve. The valve idles the car fast when cold, as the antifreeze gets hot the valve drops the idle down.....I have successfully cleaned several of these valves and cured the dying problems...
First remove the air filter top cover and the tubes that connect to the throttlebody. In the right throttlebody you will see a port right before the butterfly. Under the throttlebody you have a black plastic sensor with a 2 wire terminal. Remove the 2 phillps screws and pull off the electrical part of the valve. you will feel a magnetic pull while removing. Remove slowly and catch the black sealing oring, and there will be a metal washer also.. The shaft that is exposed is the mechanical control of the valve. Rotate the shaft and it should feel sticky if bad..Using a throttlebody spray cleaner spray into the small square port of the right bore, rotate shaft and spray until stickfree.....Reassemble

try chem12 spray. Clean mas, then spray into intake manofold w/engine runnign at 2k rpm. Check for oil leak in spark plug recesses causes a miss that the computer picks up and tries to balance.Did this to my car. it works
