    1992 Range Rover starts up runs fine but after warmed up and shut off by key won't start for at least 2 hrs. Rick Please help


    sounds to me like the cat converter is stopped up. Usually the engine will die out after a short while though if it is clogged. Over time the pressure will release enough for the engine to start again. The coil could be getting hot and fails to spark, but again this should kill the engine after a short while. If you let the engine idle will it die on its own? more info if you can supply any would be great.

    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

    I have a 1999 Range Rover with the Gems 4.0 engine. When I start the engine it goes to around 1800 rpm at idle and will not come of that rpm. What could be the possible causes


    There are 2 most probable reasons for a high idle : Vacuum leak and IAC motor (Idle Air Control) is stuck in the wide open position. The vacuum leak could be a broken/cracked or hose that came loose or intake gasket could be leaking. Usually the IAC stuck open will have a code stored, but the best way to test it is with a good scan tool. A cheap (less than $500) scanner will not be able to test it, but any decent shop should have a scan tool capable of controlling the IAC to test it.

    1992 ford 3.0 liter has fast idle


    That isn't alot to go by but you may have a broken throttle return spring, sticking throttle cable, a TPS(that is out of range), a vacuum leak, a defective IAC valve(idle air control valve) and/or maybe the engine light is on. If so have it scanned for codes. Good luck.
