Probably needs the throttle body cleaned. A manual cleaning takes about an hour and is very simple if you have any mechanical knowledge. There is an article at www.trailvoy.com with picures made by one of the members. Read More
I have a 01 Buick and the ac temp that comes out of the vents is around 50 deg - at idle and around 45 deg at highway speed - Is this normal a normal temp? or should the ac temps be colder? Read More
The idle speed control solenoid controls the idle of the engine when the air conditioning is engaged. Since the ac pump draws down the engine idle the solenoid increase the idle when the ac is on. Read More
When the ac is running the idle should be raised to compensate for the extra load. If the idle isn't rising then the car will cut off. Read More
An engine usually has a higher idle speed when the ac is running. If the high speed idle does not operate then the ac will cause the engine to stall. Read More

I believe that kicks on when the AC is turned on to raise the idle to compensate for the AC compressor load. Read More
AC idle compensator. Many vehicles have a sensor that increases idle speed when you turn on & add more load. Sounds like your idle not being adjusted. Have your mech check it. Read More
Fast idle motor is not working. This is allowing the idle to fall below the threshold of what it should be when the A/C is on. Read More

There is no adjustment for this, Your need to look for a vac. leak at the throttle body /intake gaskit or the (IAC) Idle Air Control Motor or the control switch at the AC compresor, Also check for vac. leaks around the hose for youre EGR system. Read More
The engine idle may be set to low to compensate for the AC compressor starting up. Rev the engine a few times to see if it stops. If it doesn't, there may be a problem with the AC temperature signal or motor mount. Read More
Idle slows down to a stall when you stop or slow down when AC is running. How do I adjust idle or is something else wrong? Read More
Is it a 4 cylinder? Sometimes a 4 cylinder engine will shake a little extra when the AC is running and it's at an idle. You might be able to step up the idle a little extra but 4 cylinder engines are notorious for shaking when the AC is running. Read More
The most likely answer is that the refrigerant in the AC system has slowly leaked out and can no longer work at low speeds. Read More
When you turn the ac on it engages the ac clutch which is turned by a fan belt which is turn by the engine. you are making the engine work harder. The idle speed might be set to low or it,s time for a tune up. Read More
Throttle position sensor. With the AC turned on, it causes a greater load on the engine, and a slightly decreased idle speed. The throttle position sensor would detect this immediately and raise your idle to where it would normally be if the AC wasn't running. Read More
Yes they can. It can also be a vacuum leak, or defective idle control valve. Read More
When the AC is on most vehicles increase the idle speed. That can often mask the problems that cause rough idle. The primary suspects are: EGR valve, tune-up, sticky or plugged injectors and valves. Read More
the ac slows the engine, the lower idle causes the lower oil pressure Read More
An idle motor controls the idle-like when U turn on the AC,It will raise the RPM's so the engine doesn't stall. Idle motors are used on computer cars & instead of a screw adjustment. Read More
Give the engine some extra fuel and see what happens when you turn on the AC. If there is still a problem then the compressor or AC clutch could be bad. If its ok then the fast idle needs to be looked at to find out why the car does not idle up when the AC is on. Read More
The idle is set too low or there is an electrical problem Read More
You need to adjust your idle. Read More
The A/C uses more power, and raises the idle RPM Read More
Why would your engine Idle fast and slow when you put your air conditioning on in your Toyota Pickup?
The idle compensator speeds up the engine when the ac is turned on to compensate for the additional load on the engine. If the engine is surging when the ac is on and not any other time then the compensator is probably bad. If it surges all the time but gets worse when the ac is on then look for an intake vacuum leak. Read More
Idle compenstor Vehicles hve an idle copensator that speeds up the engine when the ac is turned on to ring the rpm back up to the proper idle speed, if yours is too fast then t needs to be adjsted. Read More
if the ac was on it could lower the idle down the ac takes about 12 horse power to run + As long as the transmission is in "Drive," it provides excess strain to the engine system and at a stop will keep the engine idle a couple hundred RPM lower than in "Park" or "Neutral." Read More
700 to 750 rpm is normal. if the engine stalls, you may have to replace the IAC (Idle Air Control) Motor. they get stuck. Read More

Was there any recent work done to the car? When did the idle problem start? Does the idle get worst when you turn on the AC? Answer these questions and then I may help. Read More

Why does your 2002 Pontiac sunfire jump as if trying to accel when stopped and the ac is on and also stalls when stopped doesn't do either of those when ac is off?
The idle is designed to increase when the A/C (higher engine load) is on....see if the local library has a shop manual with a section on this idle control system...may be just a simple idle/throttle plate adjustment, also, check the timing...Good luck:) Read More
Why would a 1996 ford explorer make a loud humming noise when warm and going slowly or just after AC is turned off in the heat?
The idle air controler valve needs to be replaced. I've got 2 explorers, 98 and 01. It's really easy to replace. Just google 'idle air controler valve explorer replacement' should set you back about $50 at autozone. Read More
make sure your electric cooling fan is working when the air is turned on. Read More
You cannot. As it is EFI, therefore controlled electronically, you would need to plug it into a diagnostic computer to access the idle speeds etc. Read More
When I turn on the air conditioner on my 2006 ford expedition does the idle speed drop down to 400 rpm?
Your AC pump runs off of a belt that will drain power from your engine, thus lowering your idle. You can see it if you pop the hood and then watch the belt start spinning when someone in your car turns on the AC. Read More

Most likely cause is an inoperative condensor fan. Read More

It's expecting the AC compressor to kick on to help the drying process. If you don't have AC, then I'm puzzled too.. Read More
check coolant level clean throttle pate if you have ac the condenser will cause an idle change about once every 20 seconds Read More
Yes, and an overcharged AC can cause devastating damage to the AC system. This is why you should have a certified shop perform this operation. Read More
Why does car cut off at a red light or stop sign while the air is on but if its not on it doesn't what could that be?
could be a combination of a non working idle compensator and a vacuum leak. Poor vacuum will cause your car to stall at a light, the brake booster runs on vacuum, this together with the added load of the AC with the idle not being raised by the idle compensator might cause this to happen. Check your vacuum lines, especially the one going to the brake booster, and check to see if when you turn… Read More
