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?
View 3 RepliesMy toyota will not idle. The last time this happened, it needed a new battery. The idle is controlled by the battery. The alternator doesn't kick in untill 1500 to 2000 rpms. The battery checks out OK this time. It's an 03 4cyl.
View 5 RepliesTitle 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.
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.
I get a really low idle, almost to the point of the car stalling, when the A/C is on. Usually it's only when I first start her up but sometimes I notice it at stop lights after driving for a while. The idle goes back to normal when I shut the A/C off every time.
View 1 RepliesI recently bought a 2014 4-cylinder SE, sight unseen. I test drove another 4-cylinder SE that I recall idled smoothly before I bought mine - or at least I did not notice it, but this one was a trade from another lot and had all of the options that I wanted.
So - is it "normal" for the 4-cylinder Camrys to idle very rough with or without the A/C on, and in drive? I have tried a tank of 87, and a tank of 93 octane. Very small difference in smoothness on 93 octane, but I'd prefer not to have to run that. I owned a 4-cylinder 2008 Chevrolet Malibu before this car, and it idled much smoother than this Camry.
I also have a weird grind that sounds like the starter isn't disengaging when I start the car in the mornings. Push-button start on my car, so it isn't me turning the key too long or anything of that sort.
I just bought a 2009 Camry LE (4 cylinder) about a week ago. It's only got 10K miles on it. Ever since I got the car, I've noticed a very slight vibration when stopped and in gear. It does this when the engine is cold and warm. It only does this when I am in gear with my foot on the brake and stopped. I still have warranty, should I bring it in to the dealer? Is there a simple fix for this? Or is this normal?
View 14 RepliesFriend of mine drives a 2008 Camry with 2GR FE engine, with 65 000 miles. When the engine is cold it runs fine but when is fully warm it idles low, in D or R at around 560-600 rpm. When he shift from P to R or from N to D, the idle goes down, not up like it should. The spark plugs are new, air filter is new. No CEL.
View 10 RepliesI made a post earlier about rough vibrations at idle on my 07 camry le not too long ago. I cleaned my throttle body and it worked, but now they are back and worse then ever. Now the vibrations go in and out, like it vibrates for a second the stops for a second then starts vibrating again until I move and stop at the next light and then the in and out vibrations are back. Also sometimes I hear metal hitting sounds.
Just had an oil change and oil changes are always on time so I doubt it's the engine knocking. Also when the AC is on the vibrations just become very unbearable. Finally sometimes when I turn the steering wheel while barely moving or not moving at all the vibrations get as bad as when the AC is on and very noisy. Also I noticed turning the steering wheel raises the rpms but then drop back. I tried to record the sounds, but as usual video of sounds are useless.
I have a 2008 Camry, 2.4L, and used the spark plugs change DIY sticky and it seemed to go painlessly. However, after the new spark plugs, the car seems to idle rough. It has 95k miles, and I did the following in the same tune-up:
1. Changed Oil
2. Replaced Air Filter
3. Changed Spark Plugs
4. Cleaned Battery Terminals
5. Cleaned MAF Sensor
6. Cleaned plugs connecting to ignition coils
I used OEM Toyota plugs, and even called the dealer to see if the gap needed to be set. And they affirmed me that the gap is preset on these plugs.
I changed all of the brakes on her car yesterday, test drove it, everything was great. Put close to 100 miles on it w/ no issues. Therefore, I don't think it's anything I did.on her way to work, the CEL came on. The car has a rough-ish idle, and jerks slightly in low RPM. I went to Pep Boys and got it read. it threw 8 codes:
P0171
P1130
P0300
P0301
P0303
P0305
P0442
From what i've read, the p0171 is the system is running too lean and p0442 is a leak somewhere. The 300s are cyl misfires.I don't want to go replacing every conceivable part. What these codes mean in conjunction?
The engine on my camry 2007 was overheated and I had the headgasket replaced but now it has misfire codes and rough idle this is a 2.4 engine I replaced 2 of the coils but still it has a rough idle... when the car is running it runs pretty good.
View 5 Replies2007 Camry LE. This morning while driving, she noticed a shuddering that scared her. She called me and parked the car as soon as she could. I went to drive it around and, as she had said, it was shuddering.
I drove it for a bit, neighborhood and highways, and took note of everything. The RPMs were low - About 500. I'm not sure where it usually idles, I rarely drive this car, but my Jetta idles around 900 so this seems strange to me. RPM gauge occasionally bounces around at idle. Once the car gets moving there are no issues. Only at complete stop. It feels like the car is about to stall.
I drive a manual and if I keep it in gear while approaching a stop it makes the same shuddering because the RPMs are too low for the selected gear. This is what it reminds me of.
Here is a video of what's going on under the hood. As you can see, the airbox is vibrating heavily. That's the most obvious place. The engine and intake manifold are also bouncing around, but it's hard to see in the iPhone video.

As of late, my 06 Camry (I4) idle's real rough @ 600 rpms when in park. It stays the same in drive with the A/C on. However, when I switch the A/C off, for about 2 secs, the idle will be smooth before dropping down in rpms. Some folks have said this is normal, but I've had this happened to my car before. I've got 135K on it so I'm guess a tune up is in order.
I'm new in the game of working on my car myself since a past issue with the dealer on my '06. So if all is needed is a tune up, I can do that myself with the parts of my choice.
Recently I have been experiencing some rough and low idles with my 1MZ-FE 05' Camry. The car runs idles perfectly fine and drops to the correct idle when cold, however if the engine has been running at normal temperature and started again soon after the idle drops extremely low until the throttle is opened.
I have cleaned the throttle body with with throttle body cleaner a number of times, although I haven't taken the IAC valve out and cleaned it separately. I have also heard that the Engine Coolant Temp valve may be going bad. Could my symptoms fit this?
I had a dodgy EGR sensor not long ago that was giving me rough idles on a cold start, however I managed to mitigate that problem a by cleaning simply removing the sensor and giving it a quick clean. I don't think that this is the cause but I can't be sure.
I haven't had the spark plugs or fuel filter changed in a while although I'm unsure that these would be the problem if the idle was rough and low only when the engine was warm.
My wife has a 2002 Camry V6 SE with about 75k miles. Over the past 6 months the car has developed a problem. Every so often, say once every 2-3 weeks the car will start fine, but after driving for about 5-10 minutes, will start running rough and stall if I stop for a light. It will start again, (with a little effort) and will stall again at the next stop and so on. I can pull off the road, wait 10 minutes and the car will then run like a Swiss watch until the next episode.
I have taken the car to a respected mechanic and he sees nothing obvious wrong and there is no record in the car's computer of any problem. The last time this happened the car had been on the road for about 20 minutes before the stalling problem occurred. I kept the car going at idle by putting in neutral and increasing the throttle.
After we arrived home, the car cut out when we made it into the garage but a rotten egg-like smell was in the air in the garage. After about an hour, the car stated immediately and ran like a top. That was about a week ago and no problems since. I have read in the threads about EGRs Throttle bodies etc.
My 07 camry's battery died last week and I got it jumped, drove about a mile and while at idle it felt as if the alternator was not charging the battery and It was slowly dying. Took it to Tires Plus, they said the computer forgot how to idle, so it was misfiring and threatening to shut down at every idle. 80 dollars later...it was fixed, for a week.
This morning, my battery was dead again, again from leaving a power connection unscrewed that came from my fog lights attached to the battery in the car after cleaning it on sunday, called AAA. He said that I have to get a screw to screw it back in or it will die once I turn off the engine again.
I work at a construction plant so we have quite a few nuts and washers laying around. Well it had a rough idle again, on the way to work, lights would be bright then dim again and vibrating the car, like it's struggling to keep the power.
I have been searching and it seems I am not the only one who has a rough idle with the I4. It is very rough even without the A/C on. I can see the dash shaking, I can feel it in the steering wheel, brake pedal, seat, and arm rest.
The dealership cleaned my throttle body and MAP sensor (They forgot to put one of the screws back in the MAP). This is the third time they have cleaned them. When they returned it to me I told them to keep it until it is fixed. So they took it back in and decided that it might be the motor mounts so they went ahead and replaced them aside from the dogbone or whatever it's called.
When they returned the vehicle it was still having the same issue, they told me that its just the nature of the beast and to live with it. Well my neighbor has the exact same car, and yes it does have a SLIGHT vibration in gear but nothing like mine. I can't stand this car I really wish I would have bought something else.
I currently have 70,000 miles and for the last three oil changes I have been running Full Synthetic in hopes it would work but it has made no difference.
Just a note I have had multiple problems with this particular dealer lying to me. They even ripped up my passenger seat and would not fix it they said it was pre existing. I am over the seat I don't care anymore but I am tired of the rough idle. I plan on taking into another dealer but I am hesitant because they told me if there is no real problem I will have to pay in full for the diagnostic.
I have an 2008 camry le i4 and every time I'm stopped at a red, the idle is so rough. would the dealer know anything about it to fix it? My car's about 2 months old and has 4000 miles on it
View 14 RepliesMy 2001 toyota camry is great but has an intermittent, annoying problem no one can diagnose or correct. If I drive for a while at top highway speed (say 65mph) and then have to come to a stop (to pay toll or stop light) I get a very rough idle and then the car stalls. Have had new plugs, wires, coil, radiator already done to solve problem. Check engine light never comes on. Can also drive lengthy trip and it doesn't happen.
View 18 RepliesI've made posts about a rough idle before now I noticed something new about it. I noticed when I approach a red light the vibrations don't start immediately. They start as soon as the RPMS would drop a little. They stay above 500 but it seems like it's below 750. As if the engine is slightly starved from power? Now i'm wondering if it could be related to another problem I have.
Whenever I start the car, the battery light flickers until the car is started all the way. This is on a 2007 Camry 4 cylinder. So far everything iv'e done is: New NGK Spark Plugs, NEW OEM mounts (all 4) Seafoamed the engine, Seafoamed the throttle body, cleaned the MAF sensor, New air filter, and cleaned the air filter box, replaced the PCV Vlave, new belt, new alternator (duralast), and a new battery (from autozone).
