Camry :: 2003 - Car Low / Rough Idle When AC Is On

Title tells the story....also it seems that sometimes it does this when the brake pedal is depressed -- since it is a manual 5-speed, tho., often the brake pedal is not depressed at stoplights, etc. So, 2003, four-cyl., as I said, manual trans.

It's my husband's. He has been gone. I am driving the car for him while he is away. The car seems to have had this rough/low idle (according to the tach) with the A/C on for at least a couple of years. Idles O.K. if the A/C is not on.

He returns tonight. And, I have to pick him up at the Portland, Oregon Airport.

Camry :: Low Idle RPM On 2003 Toyota

I have a 2003 4-cyl. Was running OK til starter died. Changed the starter, now it starts fine, but has idle problems similar to a dirty IAC. Sounds a lot like this thread: Low idle rpm problem on 2003 Toyota Camry: How I solved it

Haven't tried that fix yet. I was wondering if there anything else I could consider, due maybe to disconnecting the battery causing computer problems or something like that?

So I decided to run it for a while, thinking maybe the computer needed some more data. Idling about 100, but driving OK (around the block) but definitely not right.

Then the check engine light came on; I need to pull the code of course but need to borrow a code reader.....

Camry :: 2003 XLE Car Wouldn't Idle - Bad Battery

Camry 2003 XLE. Stopped @ store yesterday turned off lights locked car. Came out lights on battery dead. Portable charger started it right up. Drove home 2 minutes shut off car started right up. Went to Advanced Auto they tested and said bad battery. Went to repair ship 2 get second opinion they ran test twice that said battery and charging system OK. Said corroded posts issue. They cleaned hooked battery up and car wouldn't idle. They ran test again now said both battery and alternator bad. They also checked computer for error codes and nada. Upon advice from Toyota dealer drove around for an hour and gradually was getting better. FYI car died at least 10 times when idling during drive but started right up. Parked car and left idling with AC, lights, etc all on. Checked a couple times still running. Went out 15 minutes later car off battery again dead.

Camry :: 2003 Toyota - Low Idle RPM With Engine Heated Up

I have a 2003 Camry 4 cyclinder with about 85k miles, for the past few months I've noticed that it has not been idling at 800-900 rpm with a hot engine, but instead it was idling around 500-600rpm. Not really knowing what was wrong, I went through the following process of elimination.

1. New Spark plugs - no change
2. Air filter and oil change - no changes
3. Coincidentally found my upper torque strut mount had a crack in the rubber so I replaced the torque strut mount and 2 lower motor mounts - no changes
4. Seafoamed the intake vacuum hose and gas tank - no changes
5. Checked oxygen sensors (the check engine light was not on)
6. FINALLY did some homework online and someone with a similar problem was suggested to clean out the sensor in the throttle body with carb cleaner - Problem solved!

Here is a verbal summary of how I did it:

1. Make sure the engine is cool because it is in an awkward area so you don't wanna get burned
2. Remove the top half the air filter box and disconnect the electrical and other rubber hoses so that the plastic/rubber intake manifold can come out easily
3. Disconnect the intake manifold, it's basically the non-metal tubing
4. In the throttle body assembly (the first metal component you will encounter after the intake manifold), you will see the "hinge door", swing it open and you will see a pencil erased sized hole toward the back end, use a flash light to see.
5. I used the handle from a hair of needle nose pliers to hold the "hinge door" open while I pointed my straw from the carb cleaner at the pencil sized hole where I suspect the sensor is located and give it a few quick spurts of carb cleaner (caution! Make sure your straw is secure before spraying because you don't to lose your straw down the throttle assembly!)
6. Wipe dry with clean cloth and give it a few minutes to evaporate, replace everything and fire up the engine (it might take a few cranks to get the car to fire up). Warm up the engine and take it out for a spin to see if it has resolved your idle RPM problem

Camry :: 2003 With 4 Cylinder - Rough Idle Only At Cold Start

Camry :: 2003 Fails To Idle At Start Half The Time Randomly

I have a meticulously cared for 2003 Camry. When I got it a year ago it stalled at startup about 10% of the time, and it has increased to almost 50%. The engine light is on and off, but seems to have no bearing, nor does air or engine temperature. If I keep my foot on the gas even when stopped, I can drive it. Sometimes it warms up to idle, sometimes not. It stalls usually at start and always when going slow or stopping. Sometimes it succeeds in idling, sometimes it fails, but never something in between. Either it idles right at 1000rpm, or at 0.

Mechanic ran it through the computer, drove it around, tried it a bunch of times and found nothing.

Camry :: 2003 Camry 2.4L - Cooling / Radiator Fans Stay On All The Time

My 2003 camry LE 4 cyl cooling/radiator fans stay on all the time. As soon as I turn the ignition key both radiator fan start to spin even though the car is cold and not on. I checked all the relays and fuses. Checked the voltage on the coolant sensor harness with ignition switch on, there is no 5v or the green pin is not grounded. I am clueless where to go next.

Camry :: 2006 2.4L Car Sometimes Idle Very Low

When I make a complete stop and still in DRIVE my car sometimes idle very low; below 500rpm (engine starts to shake a little like it is going to turn off). And sometimes it does that for like 10 seconds and then picks back up to 800rpm. What is the cause?

Camry :: New Alternator - Rough Idle When AC Is On

Just installed a new alternator today, and the motor (4 cyl.) idles rough when the AC is on. The battery was disconnected during the installation, but nothing else was touched. Is this caused by the new alternator itself, or because the battery was disconnected for a while? Should I set the idle speed a little higher or what?

Camry :: Idle Too Low When Engine Started

I had to remove the battery to get at the DS parking bulb. When I reconnected the battery and started the engine the idle did not go way up like normal, but I thought it was because I had removed power from the computer and it needed to relearn my driving. Well the idle was so low it was difficult keeping it running and it did not improve.

Camry :: 2002 XLE V6 Rough Idle For A Second

So my 2002 Camry XLE V6 with ~132,000 miles has a little bit of a rough idle. It sounds like it's "breathing". It'll be rough for a second, smooth for a second, rough, smooth. It's not super rough where my steering wheel is really vibrating, but definitely noticeable. The RPM hovers around 500-600 and doesn't really fluctuate. On Sunday, the following was done with a friend:

- All 6 spark plugs with DENSO SK20R11

- OEM PCV valve, grommet, and hose

- OEM Air Filter

- OEM Cabin Filter

- OEM plenum gasket

We didn't do the head gasket and manifold gasket to save time and there was absolutely no oil on the coils or plugs. The car was very well maintained by the previous owner and by me since I got it at ~102,000 miles.

The car seems to surge sometimes. I'm not sure if that is the right word. Say if I turn left up a hill and hit the gas, the engine RPM will kind of surge up and then it'll shift. It's audibly noticeable. It's not smooth, but maybe it's just because it's a hill, I'm not sure

The idle seems about the same since before we did the plugs, which I thought doing the plugs would work. It almost seems like it might be worse and the MPG might be worse, but that may just be in my head.

Could it be the front motor mount? Maybe we should have cleaned the throttle body while we had it open.

Camry 2012+ :: Vibrate At Idle With AC On?

Wifey has been complaining the past 2 days that her car has been running a bit funny. First warm-ish day here...sitting in traffic and turned on the AC. At a complete stop, in Drive, the car is vibrating the floorboard quite noticeably. Somewhat less noticeably in park/neutral. Otherwise, it seems to behave just fine...power is fine, motor sounds like it always does.

The car was about 3/4 of the way through the tank of gas (87 oct), and wasn't running like this a few days ago when I spent a lot of time behind the wheel. I went and filled the tank, thinking maybe it was bad gas, with a fresh tank of 89. Nope...as soon as you hit the AC button...it starts vibrating.

So the question from all this...does YOUR I4 Camry shake a little bit with the AC on? A little bit of vibration from a 4-cyl doesn't surprise me, but I sure don't seem to recall it last year.

Camry :: Engine Won't Idle, Need To Keep Revving It

I am due for an inspection for a 2004 Camry (4 cyl.).

I had the engine light come on with a P2231 or P2238 code on my OBDII tool. Car was running fine, no weirdness whatsoever. But I went ahead and changed the front sensor (Bank 1 Sensor 1). As soon as I changed the code went away and it is not coming out anymore, nor are other codes.

However, the engine doesn't idle after 5 minutes running. I have to keep revving it up at the light to keep going. I shut it off and it turns on no problem. But then it doesn't idle. What a pain, I used the Bosch O2 sensor bought from AutoZone.

Camry :: 2002 - Stalling When Idle

My car (2002 Camry, 65K Miles) stalls when I take foot off the gas pedal, this starter four days ago then it worked fine couple days later and the problem is back again. I did some research and cleaned throttle body, do I need to clean or replace IAC valve and EGR valve?

I also read on the forum to check the vaccum hoses for leaks, looking for more info on location fo the vacuum hoses and how to clean or replace them?

Camry :: 6th Gen - Slow Idle After New Battery

I replaced the battery and the engine idle went from a reasonable 650 to 450 rpm's.

The engine is surprisingly smooth at that engine speed but the low idle speed makes it less smooth on take off from stop.

Right after the battery was installed one of the radio functions was backwards, AUX and CD were reversed, soon after it went back to normal.

Is there a way to reset the computer to stock, something makes me think this is the problem.
