Friend 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 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 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 RepliesI have a 2008 Toyota Camry SE with the 2.4 engine and auto trans. If I'm stopped and in drive the engine feels as if it's going to stall, the entire car "shutters". The tach reads between 700 & 800 but if I place the gear selector into either neutral or park it becomes "glass" smooth, I even have to look at the tach to see if the engine is still running! In neutral or park the tach still reads 700-800 rpm and the A/C is always switched off.
I've had it to 2 different Toyota dealers and yesterday to my regular mechanic. 1st dealer said to disconnect the battery and bring everything back to default positions...no difference, battery was off for 35 minutes. 2nd dealer said to have the throttle body cleaned, which I did...no difference. A bit of background with the vehicle, I've had it since new, I drive 170 hiway miles per day, I use Shell branded fuel, oilchanges always at 5,000 miles, dealer serviced since new.
So yesterday my mechanic checked everything, engine mounts (OK), any error codes (none) cylinder compression (all within spec) spark plugs (OK except for 1 so I asked him to change them all), he installed 4 NGK iridium plugs and guess what...it still shutters & vibrates!!
When my Camry is in DRIVE and sitting at a red light for example, my car will shake. It feels like it idles rough. If I put it in neutral the shaking goes away... only when in drive.
I took it to Firestone who mentioned I had a dirty throttle body. So I get this cleaned and the shaking has significantly reduced. However after a few months I'm back at square one. Dirty throttle body and care is shaking again. (Yes air filter is clean)
I noticed two things that I think might be contributing... After 5,000 miles my oil is pretty black and very low. (Time for an oil change) When I swipe my finger on the exhaust pipe, its really black but no black smoke comes out. I don't see any oil leaks outside of the engine, its actually pretty clean.
So two questions, is the low oil and black exhaust pipe normal? Why would my throttle body keep getting dirty?
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 RepliesRecently 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.
I purchased an '08 F150 about 6 months ago, and have a problem that two mechanics haven't been able to solve. The truck has a 5.4L engine. Unfortunately, I bought from an auction and the 30 day warranty expired before I realized the problem.
After a longer drive (30 minutes to work) the engine is warm, and I always back into my parking spot or driveway. In low gear, it begins to idle very rough and the engine shakes. If I leave it long enough, it will stall. Usually I pop it into neutral, give it some gas, and its fine. I just bought a camper trailer, so I'll need to use the lower gear when backing up.
So far, the engine has been flushed twice, the solenoid replaced and phaser replaced. The second mechanic has recommended I contact a dealer, but haven't had luck with them with my previous Explorer. What it could be? I will be getting the diagnostic paperwork this week.
I have a 2008 Ford F150 4.6L and its been broken down in our shop for quite some time now. It started acting funny when I could not get the truck to do over 80kmh. Slow acceleration, and a horrible shaking when it idled. Eventually it was undriveable since I could go above 50kmh anymore. From looking online we replaced the plugs and coils. We removed the intake to find the gaskets were shot so coolant was leaking into the spark plug tubes which could've been the cause of a misfire. Fixed that. Still the same. We replaced the egr valve and dpfe sensor because we keep getting the P0402 excessive egr flow code. Still no luck. My dad is a journeyman hes just not too familiar with newer trucks.
View 4 RepliesI have a 2002 Camry SE (V6) with approx. 180K miles. The Engine mounts were shot so I decided to change them. I am a reasonably qualified mechanic (FAA Aircraft Mechanic) and perform most my work on my cars so didn't think this would be a big deal.
My procedure was to jack up front & put frame on jack stands then removed both wheels. Then with hydraulic jack and blocks under oil pan I started by removing all or the three lower engine mount hold down nuts (3 on bottom, 1 on top of each. NOTE: I changed the dogbone first which took 5 minutes.
I then jacked up engine about two inches or so and pulled out each old mount, then lowered engine back down making sure everything lined up as best I could. Then finished by tightening all of the nuts. Done. ....or so I thought.
When I went to start, the engine cranked but with a an unusual vibration and generally rough idle, more noisey than usual. When I drive it shift fine and everything works, just unusual vibration and noisey inside car.
I also used my BOSCH code checker and got ZERO CODES.
What is even more unusual is the engine when you are outside the car listening sounds fine. Just sitting inside do I sense the unusual vibration and noisy idle.
I checked for loose vacuum hoses, anything obviously pulled loose, etc and found nothing.
Again the car started and idled fine before the engine mount change now starts kind of rough and is noisy [inside car] but quiet outside.
nothing really changed except the moving of the engine block up and down to get the old mounts out.
I have a 2008 Santa Fe 2,2 CRDi that recently started to behave bad. When cold it starts but runs only for a few seconds before it dies. The engine seems to shut off without any notice. I am able to start the car again straight away, but the same thing happens.
If I try to push the throttle I might be able to keep it running for a longer while, and it seems to improve as the engine gets warmer, but it still dies after a while. (Some minutes.) When running, the engine feels kind of rough (hard) and not a smooth as its supposed to be.
I have cleaned the EGR valve, and replaced all the injectors. I also checked the diesel filter for water and flow, but didn't replaced as it was changed this summer.
The car is a no runner as it is now, since the uncontrolled shutdown of the engine makes it danger to use in the traffic.
I just purchased my first F150, 4.6L V8, 55,600 Miles. It intermittently has a rough idle and only seems to be when the engine is hot. I've had engine and tranny mechanics look it. The spark plugs have been inspected and are within an acceptable range. The throttle body has been cleaned. There are no trouble codes of any kind. What I can check next?
View 13 RepliesAfter a long trip from Houston to Dallas, my vehicle started to ride rough and eventually die on idle. It seems to idle fine, but then die after the first minute. I am getting code P306 and others all dealing with random misfires and misfires on ALL cylinders. The troubleshooting steps I have taken so far to no avail are:
(1) Replaced spark plugs with pre-gapped iridium
(2) Checked ignition coils
(2) Checked all vacuum hoses and air intake leaks
(3) Changed air filter(not a big deal)
(4) Removed and cleaned the throttle body with carb cleaner thoroughly
(5) Checked the intake manifold for leaks and did not find any.
(6) Computer PCM checked for updates and issues at dealer
The dealer said it needed new fuel injectors, which seemed kind of fishy due to the following symptom:
The car runs GREAT at highway speeds, but it is unable to maintain an idle for an extended period of time and dies due to misfires. I hear a chugging in the engine sometimes.
Due to these symptoms, I self diagnosed this as a fuel regulator?
We have owned a 95 Camry V6 for 20 years and it has always been reliable. However, several days ago, the car started to have its first engine performance issue. When we start the engine cold, there was rough idle/engine lope. If it was warmed up for about 5-10 minutes, the car was fine for the entire day. but during this rough idle, the car jerked slightly as well if i press on the gas.
Since the symptom began, I took it to local shop A and they replaced all the spark plugs, pcv valve and air filter which did not solve the rough idle/looping problem. The rough idle continued, and few days later, I was unable to start the engine though it cranks. (at least that's what I think it does). Had it towed to shop B and they've replaced oil pump, which they thought to be the problem. I took it home, and the next morning I found myself unable to start the car.
My 04 F150 has started having a rough idle. While in park the engine will stall out with the A/C off. Also when in drive the truck will idle close to 1000rpm's. I had to the fuel filter cleaned and also the MAF sensor cleaned. Also did a vacuum check on it. Pulled the code and it's throwing a Lean Code. What else should I be looking for?
View 12 RepliesStill showing the same codes (per repairman) and still having the intermittent rough idle at low speeds when the engine is warm. It has been so intermittent that I could almost live with it.
So repair guys first replaces the VCT's and runs fine until warmed up and the problem reoccurs with the same codes. He replaces both cam phasers and tensioners today and still same problem and same codes which point to the VCT and cam phasers.
Truck has 80k, city driven, oil changed every 3k or so. Burns ethanol and still runs great at speeds over 10 mph even when this problem appears.
2004 F150 5.4 3v. I bought the truck with 102k on it, it now has 124k. In the morning, when the outside temp is between 30-50, the engine starts and runs fine. When I get to the first red light ( about 1 mile away) within seconds of the engine at idle, engine starts to run rough and CEL. Every time the code is p0351. If I let it sit in the driveway to full warm up... no problem. If I start the truck, shut it off and restart...no problem. It only happens at the cooler temps. I have changed plugs, used motorcraft, nickel antiseize, torqued, etc. Ford changed the coil, I have changed the coil, cleaned MAF. As soon as I cross the intersection, light stays on, rough running clears up, and runs like a champ for the rest of the day.
View 2 RepliesI own Camry 2008, 4 cyl, 2AZFE engine, 2400cc.
I recently, started facing strange issues,
No matter whether engine is stone cold or oven hot, it does not idle where it used to be (2 weeks ago). The car idles at ~800 RPM and the rpm suddenly drops to ~700 and engine flushes in more fuel to rev it up to 1100 rpm. Will take another 10 - 12 sec to reach ~700 rpm and the same story continues.
This however, sometimes go away, in Neutral. Once I put it in Reverse the problem becomes worse with RPM dropping every other second, as if the current in the coils is failing.
All this fuss continues, even when car is at 30 mph. However beyond 30 mph I feel nothing.
Services done in last 2 weeks:
1. Throttle body clean-- complete removal of all the gunk.
2. PCV valve changed from toyota dealer.
3. Mass airflow sensor cleaned.
4. Spark Plugs changed with new Iridium plugs from toyota dealer.
5. New Ignition Coils.
Nothing solved the idle problem - missing in the car. The mechanic convinced me that Head gasket is blown. He was indeed right as the Head Gasket had crack b/w cyl 2 and cyl 3. It was changed and car was much better. But now I am again facing issues.
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 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.
