Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Low / uneven idle problem can cause by a lot of components.

Dirty air filter

Dirty injectors + o-rings

Vacuum leak at intake manifold and vacuum hose.

Bad Idle Air Control Motor (IAC)

Low compression (170 psi + is OK)

Start cleaning and repair these trouble spots and see is there any improvement.

====

For more advance DIY'er then you may try this.

Use a can of Berryman carburetor clean to locate the vacuum leak.


SEE SAMPLE PICTURE HERE


This is a 20-30 minutes job.

Vacuum leaks can occur in following locations.


Intake manifold AND/OR vacuum lines.


Intake manifold is not accessible unless the engine head if off.

You can still check the potential leak by spraying some Berryman near the intake manifold.

Listen for rpm increase after you introduce the Berryman (FUEL) at idle.


Do the same starting from the brake booster unit (the round unit) on the drive side fire all.

Carefully listen for increase of RPM right after to spray the Berryman to the potential vacuum spot.

Get a friend to HEAR the RPM increase or monitor for RPM on the tech.

DO NOT AIM the Berryman into any heat source.


PLEASE RATE my answer if it is useful to you.

How do I fix a problem of engine cutting out when I have air conditioning on and I slow down ?


idle air control valve problem , maybe ! Clogged passage . When you put extra load on the engine , such as turning on the A/C the PCM is suppose to raise the idle RPM . With a up scale scan tool you can see if the PCM is controlling the IAC valve . There are videos on you tube on cleaning The IAC , plus testing !
PCM is the engine computer ,just in case your not familiar with that .

2004 Kia Optima idles rough when AC on; idles fine when AC off -- what is the problem?


Putting on the AC causes power to be taken from the engine, and that is quite usual (unless it's taking excessive power but if there are no noises and it's working ok that's unlikely).
That will slow down the engine (similar to switching on your heated rear window whilst idling)
What you are seeing is the idle is probably a bit slow, and it's too slow with AC on. Have a diagnostic run to check idle speed and mixture at low revs.

Idels high then low eventually cut out


combination of emissions controls and ignition control issues and mine which is a 91 does the same exact thing because the defrost controls cause the engine to rev up high then slow down.. I disconnected the ac compressor so it does not come on..mine has some vacuum issues that I have not corrected yet but as old and as many miles as is on it Im gonna leave it alone until the motor blows up ..it smokes now and has over 300,000 miles on it.. rebuilt twice..5 head gaskets..6 timing belts and even when its really cold outside, it will start up when all my neighbors' cars wont..funny as heck..

My car sounds like it wants to cut out!


sounds like your idle is set too low , check your rpm at idle (warm) , and up your revs at idle.3_30_2012_5_08_46_pm.jpg

Speedo will cut out when driving


Sounds like your "speed sensor" is failing. When it fails it will cause irregular shift patterns and engine idle speeds.

When in neutral or low rev occassionaly cuts out


it's your idle air valve located on the backside of your intake round with two large lines going to it make sure you check junkyards first for one because you'll faint when you hear the price at the parts counter.
