Toyota - Camry :: 2012 SE Running Rough And Misfiring
I bought my 2012 Camry, with 12,000 miles from the Dealership in December of 2013. The car was sold as CPO, car was purchased on Dec 30... just 6 weeks ago and I have had numerous issues with the car Misfiring. When I arrived at the dealer, the CHECK ENGINE and TIRE TRACTION lights are one and the car is running very rough as acknowledged by the service techs. For the 2nd time now, I am told they are not able to recreate the problem, so they are not able to fix it.
This is my 4th Toyota and I have NEVER had this many problems with a Toyota. Did I get a lemon? Service tech says he can't fix it unless he knows exactly what's wrong. I am asking him to check the spark plugs, check the ignition coil...and his response is that they can't just go on a wild goose chase, they need to know what they are looking for. Does this sound reasonable?
Camry :: 2009 Hard Time Starting And Running Rough
My moms 09 camry has a hard time starting and runs rough. I found out that when my father went to get an oil change, they put in 5W-30. The engine cap on the engine says 0W-20 or 5W-20. The car is at 70K and it has never had any issues, always ran smoothly, always started... until the last oil change. I have looked through the all the service logs and it seems that the last 3 services, they also used 5W-30 oil in the car.

ok,up to yesterday, my wife's car started and ran fine. but we had not driven it in about 3weeks, and it was on empty. well, my kids would listen to the radio and, i think, starting it while we were at work. anyway, they ran it out of gas. so put gas in it, 3gallons, turned the key on and off a couple of times to get a good prime. started it up, died, i figured not enough fuel, yet tried again. started, but started spitting and sputtering and idling really ruff, had to hold to the floor to keep it running. removed the maf. it started and did the same. finally, i held down the gas and brake at the same time, took off to the store, got gas, but it died half way there. got it to the pump, put more gas thinking that's the problem. nope, the same. got it home, but when i let off the gas, it idles like it's not getting fuel and dies. so, any clue what it is? remember, 3 weeks ago it ran fine.
View 1 RepliesToyota - Corolla :: 2004 - Stalling / Running Rough And Hesitate On Acceleration
I'm having issues with my 2004 Toyota Corolla with 118K. Every few weeks, the car will go through a phase where it will stall out, run rough and hesitate on acceleration. Oftentimes it is accompanied with the rotten egg smell coming from the catalytic converter. When I decelerate to a stop light, the car will stall. When I start it back up, I have to rev the engine to 2000 rpm in neutral to keep it from re-stalling. Once I get up to about 10-15 mph, the car will jerk and sputter, and at 40mph, the jerking motion gets worse. If the car doesn't stall it'll run rough and have the rotten egg smell. I'm assuming the smell is from unburnt gas.
I find it happens more often when I don't let the car warm up for a few minutes. I've taken it to my mechanic, and i've gone through 2 MAF sensors, cleaned the throttle body. I changed the iridium plugs at 102K and am on top of maintenance with filters, oil and such. Of course when I bring it to the mechanic, the problems don't show up, and we are kinda blind to what could be causing the issue. Also, if I park it for a day or two after the issue occurs, the problems go away. What to look for?
Toyota - Sienna :: 2001 XLE Started Running Rough When Weather Turned Cold
I have a 2001 Toyota Sienna xle that started running rough when the weather turned cold. When started, the car idles very high and will not shift properly until it was been running for around 5 minutes. After that it will run well for about 10-15 minutes and then begin to run rough or poorly. The problem is very noticeable at low speeds and when stopped. It never actually kills, but it feels like it is going to. At high speeds it is less noticeable but occasionally you will feel it jerk or chug like the transmission is slipping or a belt or something.
I took it to a mechanic who checked the codes and found that the ignition coils were supposedly bad. I say supposedly because they replace three of the ignition coils and the problem still persists. I then took it back to the mechanic who then told me it was the oxygen sensor. The o2 sensor was replaced and the problem is still there with no noticeable improvement. I again to it back to the mechanic who tells me that they scratching their heads.
I have done some looking around on the internet and have found some discussions that seem to have some promising leeds and actually last weeks car talk show had a caller who described a similar problem. The guys told him it could be a oxygen sensor but they thought a better possibility would be EGR valve or a vacuum leak. Not sure if this sienna has an EGR, but I plan to suggest looking into it to the mechanic. Also, I found some discussions talking about the idle control valve and the engine control module.
Corolla / Matrix 2009-13 :: Running Rough When Idling In Drive
My 09 corolla is running rough when idling in drive. It doesn't happen in park or neutral.
View 5 RepliesGolf/GTI VI :: 2009 GLI - Running Rough / Engine Seems To Chug A Little When It Was Cold
About a week ago I purchased a new K&N air filter for my '09 GLI (6spd stick & all factory options with 55,000k on the odometer). Outwardly the vehicle seemed to run better (although a new clean air filter of any type will make a vehicle run better) however, 2 days later I noticed that the engine seems to chug a little when it was cold. Not missing like a plug wire off but a chug where it surges forward then holds back continually until the engine warms up. This persists today. I've also noticed a little bit of a rough idle. I've re-inspected my installation and nothing seems to have come loose and the filter fits perfectly.
View 9 RepliesCamry :: 2002 V6 LE 1MZ-FE - Rough Running At All Speeds
I have 144,000 miles on my V6. Just started to notice that the car is surging/hesitating at just about all speeds. It appears to idle fine and if you raise the RPM in neutral I can't detect a problem. If you place the trans in drive, apply the brake and raise the RPM to 1000 to 1500 the engine's RPM varies slightly and regularly, it not steady like all of my other cars. When you are at highway speeds you can feel the car slightly buck, if you take it out of overdrive it is more detectable due to higher RPM. I do not notice the problem when the engine is cold.
I have a hand-held scanner and I see no codes and there is no CEL illuminated. I changed the plugs with OEM plugs at 90,000 miles when I changed the timing belt. Changed the air filter probably 10,000 miles ago. Just cleaned the MAF sensor (after the problem started), no change. Took it to the dealer. They discovered broken motor mounts which I kind of suspected I had, but I didn't feel the symptom were mount related. They said that I was feeling torque converter lock-up. I told them that the range of speeds and gears that the problem presented itself that it was unlikely lock-up.
Alldata suggests that it is a fuel problem and Toyota has some TSB's for drivability. I'm discounting the TSB's because this just started recently. Any hints as to where to try first? EGR, fuel regulator, fuel pulsation damper, injectors, spark plug coil packs, ..... It gets too expensive to just remove and replace the sensors that deal with the fuels system. I have plenty of tools plus a volt-ohm meter and a fuel pressure gauge.
07/21/2009 : While I was at work I added Seafoam to the gas, tank was half full.
On my way home from work I disconnected the EGR Position Sensor connector and the symptoms disappeared and the expected CEL illuminated. When I arrived home I went on Alldata and looked for an EGR system test. I found two, one for the position sensor and one for the EGR temperature sensor.
I had to run out to Sears to pickup a vacuum pump. I performed the tests below up to the point that I needed the pump. I also removed, inspected and reinstalled the EGR Position Sensor before I left for Sears. I did not notice the symptoms on the trip about 14 miles round trip. I'll see if I still have the problem on my way to work tomorrow.
Performed the on-vehicle inspection as listed on Alldata
EGR Position Sensor resistance: 2.6 ohms, in spec
EGR Position Sensor power: 5.0v, in spec
EGR Position Sensor output with no vacuum applied: 1.0v, in spec
EGR Position Sensor output with 5.1 in Hg vacuum applied: 4.0v, in spec
07/22/2009 : Problem seems to have gone away, no bucking or hesitation. Maybe the connector contacts were dirty on the position sensor. Will update if the symptoms return.
09/07/2009 : Noticed that I am getting 2 miles per gallon more than before I found the problem.
Santa Fe (CM - 2007-12) :: 2009 - Rough Running And Won't Kick Back At Speed
I have a 2009 SantaFe Diesel and am having a few issues.
Firstly, of late it has been running rough when I back off the accelerator but hold the current speed. Almost like a mis-firing feeling. AT about 1500 RPM
Secondly, I was driving down the freeway recently, the car started to labour going up a long hill, so I tried to kick it back a gear using the accelerator but it wouldn't do it. It stayed in top gear and struggled. I had to manually do it with the gearshift.
About 12 months ago, I was having problems with the car completely losing power on a quick takeoff from standing still (say at a roundabout) but that seemed to fix itself.
Jeep - Cherokee :: 2009 - Engine Is Running Rough / CEL Code Is P0152
I have a 2009 Jeep Grand Cherokee. Engine is running rough. Check engine light comes on. Code is P0152. The code is defined as high voltage on the front o2 sensor (bank 2). I hooked up the scanner again and checked the voltages. Both O2 sensors on bank 2 are never making it above 0.1V. That seems to contradict what the DTC is telling me. Is that somehow related to the fact that it is not going into closed loop? I'm a little confused.

The truck always ran perfect till two days ago. went to start it in the middle of the day , it would barely start, when it did it was missing bad. then seemed to clear up a little after about 30 seconds but still missing. they thought they got some bad fuel. so they dropped the tank cleaned it all out and got new fuel, no change.
Him and a so called mechanic "kid from fire stone" played around switching coil packs around from the injectors with no change. He tells me that the two front cylinders , one on each side are not firing. that those two spark plugs are coming out fuel soaked after running the truck. He thinks it dropped a lifter or push rod popped out of place.
I took my A/E over and came up with codes p0106 - map sensor, and p0135 - 02 sensor. i cleared them and started the truck, shut it back off ran codes again. He also said they pulled the 02 sensor and it still ran the same.
Camry :: 2002 V6 SE Running Rough And Stalls At Idle
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.
Camry :: 2005 - Running Rough And Dies Without Foot On Accelerator
So I have a 2005 Camry XLE, 3.0 l V6 with 160k miles. The car was running fine, but I decided to change the spark plugs today (overdue).
I went through the headache of removing the intake manifold, throttle body etc and everything seemed to go OK. I reassembled it all and now it won't idle properly.
It seems like a vacuum leak issue to me, but I have double checked the multiple hose connections. I did NOT disconnect the battery at any time.
I can Rev it up to 3 or 4000 rpm and it runs smoothly (all the cylinders seem to be firing) but it runs rough and dies without my foot on the accelerator. Also I noticed the exhaust manifold got cherry red like right now... after only a minute or two of running.
Are there any troubleshooting checks I can perform to narrow down the source of the vacuum leak?
Toyota - Yaris :: 2009 - Rough Start And Idle
I just imported an Toyota Belta (Yaris) 2009. When starting it after it's been siting for a while (i.e. over night) it almost always doesn't start on the first attempt, but will on the second, recording attached.
Also, it has a rough idle. Today it idled down so low when we were at a stoplight it sounded like it was going to stall.
We've changed the fuel filter, spark plugs, and cleaned the injectors and throttle body. The mechanic has run diagnostics which didn't indicate anything other than rough idle.
Accent MC (2006-11) :: 2009 - Running Rough At Idle And Would Crank Hard / P0496 Code
Check engine light had come on, the car was running rough at idle and it would crank hard. So I threw my code scanner on it only to find out it wouldn't link. Drove it to O'Riley's and had them pull the codes. It ran rough and had next to no power on the way there. O'Riley's pulled the codes and we got a P0300 (random multiple misfire), P0301 (cylinder 1 misfire), P0302 (cylinder 2 misfire), and a P0496 (EVAP emissions system high purge flow). So once I got it back to the house, she told me that she had the codes pulled once before and that they told her it could be her gas cap so she replaced it. She also stated that she had replaced the plugs about 3 months ago.
So with new gas cap and new plugs, and these codes, I did a bit of research and come to the conclusion that it'd replace the purge solenoid. The solenoid was making a pretty loud ticking noise and when I pulled it off, it rattled so I figured that was the fix. Pulled her plugs and you can clearly see that cylinder 1 was running VERY lean and cylinder 2 was a little richer but still too lean. Plugged the plugs back into coils and laid them on exhausted. Turned the car over and we had spark. Lead me to think the misfire had something to do with the P0496 EVAP code. Put everything back together and erased the codes. Gave the car back to her and told her to let me know if the light came back on. That was Wednesday last week. Sunday she told me the light came back on and the only code that came up was the P0496 again. When I gave it back to heron Wednesday, it would still crank hard but would start.
Battery is new and checked good, alternator is pulling about 14v and checked good and the starter checked good. My dilemma is the code and the hard crank. She told me that it only cranked hard for her once so I am assuming that has gone away but we're still left with the P0496. I am not 100% sure as to how this system operates but I understand it for the most part. She told me that she had just put gas in it before the light came on. Not sure how much time had elapsed after filling it and the light coming on but I do know she put gas in it. If it's a high purge flow, that makes me think there may be a leak in the system but I'm not sure where to go from here without throwing a bunch of parts and money at it.
Camry 2012+ :: 2013 SE Running Rough After Forward Gear Shifts
This car runs rough after forward gear shifts unless I give the accelerator a push. Seems like problem is at lower RPM after shift. This condition improves after 30-40 miles. About 60K miles now.
View 11 RepliesCamry :: 2003 Rough Running / Flat Spots / Lack Of Power
I have a 2003 MCV36R Camry SPortivo, Australian spec. Have owned it for 12 months. Have had power issues.
Replaced:
plugs
fuel filter
O2 sensors (engine)
MAF sensor
Throttle Position Sensor
Have checker EGR valve - all looks good
Have coded OBD II, no codes coming up
Current issues are:
Flat spots from 1000rpm to approx 3000 rpm (esp on gear change from 1st to second)
Once flat spot stop, it powers up enough to throw you back in your seat.
Also, rough running when sitting on constant speed, esp bad between 65-85 Km/h.
Have recently done a 800km trip. half way through, isolated the EGR valve. Running probs have improved greatly, but still lacks power.
Corolla / Matrix 2009-13 :: Toyota LE - Vibration / Rough Idle Low RPM
Basically when the car is in D and when i am stopped with the brakes pressed on at a stop sign or a red light, the car starts vibrating and i can see the the rpm going down and then receiving back up and going down again something when the car is in R. its a 2009 toyota corolla le 90k miles. when the headlights are on, the rpm stays high so the car does not vibrate or anything. other than this the car runs perfectly fine.
View 1 RepliesToyota - Camry :: 1999 LX 2.2L Died While Running Now Won't Start
I have a Camry 99, LX 2.2L (99k miles on it) that just died while I was puling out of my driveway. Unfortunately, it wont start anymore. I had problems with alternator for the past 2 years. Last year I just replaced the alternator and the battery. It all went well after that. A check engine light for EGR Valve came on, replaced the valve but the light comes back after 30 mins. Anyway, the car runs so I ignored the check engine light. Then this problem occurred. Before going to the alternator replacement again, I first did a tune up.
Replaced all 4 plugs, high tension wires, and the coils. The engine seems to choke at first start, then the rest of the trials are the same old cranking. The battery seems ok, pulls 13.8v when the engine is not running (I couldn't make it start anyway). I could not check the engine light too because the engine wont start. I may say I'm the guy who do small repairs, changed my own timing belt and water pump and do my own oil changes. But this one caught me on a dead end.
Camry :: Rough Idling Engine On 2002 Toyota SE
Our '02 Toyota Camry with 92,000 miles has been idling rough for awhile. I tried cleaning the throttle body which actually seemed like it made it worse for awhile. I do need to replace the valve cover gasket and I don't think the spark plugs have ever been replaced. Is that a good place to start?
