High idle after engine is warm. nothing is sticking with linkage.1992 chev k1500 5.7


Make sure the idle screw was not turnned causeing tps sensor to read over the spec limit, the next then is to make sure the idle air control valve is working , a bad valve will cause this problem and last is the stepper motor that controls the idle. some of these around this year used steeper idle control motors instead of idle air control valves and in turn the stepper motor is bad it will hold the throtle plate open to much causing the tps reading to be wrong triggering the engine light to come on. the steeper motor will be boltted to side of the throtlebody and theres a small arm to the throtle linkage. i will enclose a stepper motor picture and an idle air valve to show you, but this sounds like the tps is out of range due to this. the last thing is to make sure there are no vacuum leaks, spray crab cleaner around throtlebody base gasket and also the intake mounting gasket and see if the idle changes is so theres a vac leak in that area. good day. okay just did a little research and this truck does have a idle air control valve, the picture is encolsed and is screwed into throtlebody, check that and for vacuum leaks, make sure tps is good sometime it will test good when testing and go bad when it wants, you could have a bad tps and idle air control valve also.11_27_2011_9_27_54_pm.jpg

My 2000 ranger idles really low and sonetimes even dies. ihave to push gas pedal little bit to get it started


The Idle Air Control (IAC) is not working.... This is a very common problem and very easy to fix. The IAC will run you about $50 (USD) and the only tools needed is a 8mm socket. Disconnect the electrical connector, remove the 2 8mm hex screws, remove IAC. Reverse order to install.

It looks like the picture below

Have an automatic transmission, 2001 Kio Rio. Problems when idling, sometimes high, sometimes low and will stall but starts right back up. I've replaced the Mass Air Sensor, spark plugs, air filter, coil....


It sounds to me like you have replaced everything except the most likely cause of your idle control problem...The Idle Air control. (IAC) (or Idle Speed Control Valve) It is located onthe throttle body and looks like the picture below.

Engine idle speed


Sounds like you idle air control valve is starting to mess up. You can actually take this off and clean it with throttle body cleaner and it should help get your idle back to normal. As is sounds the idle air control valve controls how fast/slow your car idles. It is located on the throttle body normally held on with a couple of screws. The throttle body is where the air duct hose coming from the air filter box ends at the engine block. Here is a picture of what you are looking for: a483326.jpg
Make sure that you clean the valve portion and not the electrical plug with the throttle body cleaner. Let it air dry or blow lightly with compressed air before putting it back on. Let me know if you have any more questions. Thanks for using FixYa!
