HJ61 Sahara problem

Hi Dasha,

I have one of these engines too, but I suspect your problem could occur to any non computer motor with airconditioning.

I am assuming you are saying the car revs higher at idle.

There is an adjustment that you set the fast idle speed, so when the air conditioner is on, it increases the idle speed of the motor to the normal idle speed to compensate for the increased load of the air conditioner compressor. You will find the solenoid/activator on the 12HT motor on the air filter side of the motor on the cables from the accelerator pedal that activate the fuel pump. It's cold and dark outside now otherwise I'd go and look and see whether it is electrical or vacuum operated. Either way, it's a rod with adjusting nuts on it that push against a paddle.

I suspect it is way out of adjustment and sticking on. Maybe it's been bent by a wayward stick or something.

Try leaving the engine turned off but the ignition turned on, find the lever and get someone to push the air cond button on and off. If it is working correctly it should move a short distance then back when the switch is off.

Dasha,
Is the engine warm when that hapens? If it is cold, it will keep revs up, at about 900RPM, untill it warms up.
