Most likely cause is an inoperative condensor fan.
You could be low on power steering fluid
The Idle speed control serves a few functions such as increasing the idle when the vehicle is cold to keep it from stalling. It also responds to increased engine load such as when you turn on the air conditioning or turn the steering wheel at idle. Without the idle speed solenoid the vehicle would stall nearly every time you came to a stop.
To adjust the idle on Mazda 929 from 1992-1995.......on the top side off throttle body there is a idle air screw,turn screw cloclwise to reduce RPM. Question...is idle always high when hot or cold?
to turn on the high idle you must run a wire to the ecm /www.kennedydiesel.com:.webloc if you go to this link it will give you the instructions to do it. I did it on my truck and it works great !!! if you have a car starter with an available output you can connect it through that and run you high idle from that.
is this happening when car is at idle? the indicators use power so sometimes at idle the amp meter will fluctuate because of this. if this is happening when driving i would have alternator and battery checked
Turning the lights on put a load on the alternator causing the idle speed to drop. I would have the battery and charging system tested to make sure everything is okay. The battery may be on its way out.
adjust the idle screw on the drivers side of the throttle body turn it to the right to lower you idle turn to the left to raise it
Hi there, there is no idle adjustment on this vehicle. The most probable cause is a leaking throttle body gasket, or a bad Idle air control. A stuck open thermostat will cause a high idle in cold climates. Good luck and let me know you find wrong.
More than likely the Idle Air Control (IAC) is defective.
the idle air control valve most the time
Turn the Idle Adjusting screw.
turn the idle screw!
