Camry :: 2006 - Idling Very Rough
Nov 23, 2014
My Dad Purchased an 06 Camry, 2AZ-Fe engine w/140,000 miles on it from a family member. He was told that the engine had some issues but wasn't specific about the problem. He recently passed and left the car to me. I used to be a mechanic but i have little knowledge on Toyota. The car cranks/starts easy, but idles very rough. I scanned it and the codes I retrieved were p0300,0301,0302,0304. I haven't done a compression test or a leak down yet, but plan to tomorrow. I also will check resistance on the coils and check the condition of the plugs. I looked through some old posts on here, and seen this engine has head bolt issues. pcv issues. and oil consumption issues. Should i pursue trying to fix this or leave this project alone.

My car is a 94 camry, but has a 96 1MZ-FE engine from a avalon. Bought used and has been a great car for ~3 years. Just hear last couple weeks, it would start running and idling rough for a few minutes at a time. The last time I drove it home, it completly stopped on me on the side of the road. It finially started to make it home and now have in the garage. Now it will crank, but won't start. After you crank it, shut iginition switch off, then back to start position, you get a pop out the exaust pipe. From these forums and my haynes manual, I've checked the camshaft sensor, it appears ok (1.1k ohms), crankshaft sensor (2.0 k ohms), 3 of my coil packs, front side (1.4 ohms) manual says .5 to .85 ohms, so i'm not sure about this, the mass air flow meter (2.9k ohms), and it has the 5 volts to it, coolant temp sensor (2.3k ohms), replaced this last year. I haven't checked fuel pressure, since I have to go rent a tester.

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?

I have a 2001 4 cyl Camry with about 147K. I bought the car from the original owner a few weeks ago. The check engine light came on. The car idles very rough at low idle (e.g., while stopped with transmission in Drive). My mechanic changed out the EGR and another air flow valve that was apparently stuck open too much of the time, and also the engine idle air control valve. The check engine light is now off but I don't think it was related to the rough idle because that started before the check engine light. I have seen other forums that discuss the rough idle related to fuel dampener and also weak/broken motor mounts and haven't checked those out yet.

I have a 2006 Hyundai Accent that won't start. My wife was driving home the other day, and while she was sitting at the light she said she noticed a sudden change in the idle. She said the car starting shaking a little and idling really rough. When she tried to accelerate after the light changed, she said the car sputtered and would barely go.
She was only a couple of blocks from the house so she continued home. The car made it the rest of the way home, but she said it never went over about 5 mph even though she was pressing the accelerator as she would if she were going about 30...the car just never responded. When she pulled into the garage the car died as she was turning. Now it will crank but it won't start at all.
I tested the crankshaft position sensor with my multimeter and it was bad. I bought a new one and put it on, and I tested it immediately. The new one works, so I plugged everything back in and tried to start the car...nothing, just cranks and won't start. It's getting fuel and fire as well (tested both), but it's not hitting on any of the cylinders.

When coming to a stop in my 2007 Hyundai Sonata GLS with a 2.4 4 cyl engine all of a sudden you get something that acts like the car is jerking or surging or rough idling or something. Hard to tell exactly which but if I put it in neutral and rev the engine a little it smooths out. Only happens when coming to a stop. What caused it?

So recently my 2009 hyundai accent has been idling rough, and has been very sluggish when accelerating. Usually the rough idling is the worst when the car is first turned on and tends to tone down as the car keeps running. I had the codes red and I believe it was C0302 C0303 C0304, saying that cylinders 2-4 were misfiring.
I replaced the spark plugs which didn't fix the problem, although cylinder 4 did have a small amount of oil above the spark plug and a little bit more below the spark plug, I am not sure if that means anything useful or not. I don't have a way to check the coils directly but I swapped coil 2 with coil 1 and checked the codes again and it was still cylinders 2-4 misfiring, so I would imagine that means the coil isn't the problem. I then tried spraying WD-40 around the vacuum tubes, and if the intake manifold is on the back of the engine I tried spraying it around that gasket as well, but I didn't notice a change in the idle speed.
At this point I am not entirely sure how to proceed, from what I have read the issue causing a misfire would be either there isn't a spark, which seems unlikely at this point, or the mixture of fuel to air is wrong. That is the part I am unsure of how to diagnose/

I have a 2006 Dodge Stratus with approximately 104,000 miles on it (most highway) and I'm at my wit's end trying to figure out my rough idling situation. When I was at stop light, I would notice a rougher than normal idling but not to the point where stalling would occur. The timing belt was just replaced a year and a half ago and I thought maybe something was wrong with the alternator??? I took it into the shop and they replaced my engine mounts, replaced spark plugs, and did a fuel injector cleaning....? Well not exactly....now the idling is 10x worse to where my entire steering wheel is shaking when I'm stopped at a stop light! The car itself just sounds rough.
No check engine light is on and the idling isn't nearly as bad as when I park the car....a part of me wants to throw in the towel and say it is what it is, but I just have a feeling that something's just not right.

So I bought my accent used a couple months ago. It is a 2007 SE 3dr 5spd manual. It ran nice during my test drive and the price was right so I bought it.
Now I'm wondering if there is any way to find out the service history on the car...at least the major one's (30k, 60k)?
I ask because recently the engine was idling a little rough and it threw a P0302 code so I changed the spark plugs and holy-cruddy-deposits-batman those things were black. Gapped the new ones and popped them in and its a noticeable difference. My CEL keeps coming on and throwing a P0496 code as well, virtually once every tank of gas. Its not the gas cap so my next step there is to check the PCSV and hoses.
With these little problems, it makes me wonder about any larger issues. I know the timing belt on these things is supposed to be replaced at 60k. Additionally I would be willing to bet that my ECM software is out of date. Would Hyundai have records for any of the big maintenance milestones since they are required for warranty work?
How much does it cost to have a dealer check your ECM software and update it if needed?

I have a 2005 5.4 F-150. First off it came to me on a rollback because the owner tried to replace his plugs after he noticed it missing and of course broke one off. So after I extracted the plug from #8 cylinder and installed a new plug I cranked the truck and it was idling very rough and had a terrible miss around 1200rpm. I pulled the codes and got several misfire codes and ignition coil faults on #5,6 and 7 cylinder. Popped in 3 known good coils in these 3 cylinders with no difference.
On Mode 6 on my diagnostic software you could watch the misfire count steadily increase on #7 and every now and then there would be a single misfire on #5 and 6. It also had several codes for O2 sensors biased, stuck rich on that bank. Well since it had a brand new plug and coil, I popped an injector in #7 and havent had a single misfire on it since and it also started idling alot better and all the O2 codes went away. The problem I am having now is #5, 6 and now 8 will randomly misfire, sometimes build up a steady count on one of them, sometimes just skip around between them.
The truck has brand new plugs in all 8 and new coils on this bank also. The truck has 115,000 on it and does have some cam phaser noise on the bank causing the problem, but its not too terribly bad, I have heard alot worse. My problem is something on that bank only as the passenger side bank is fine. I am wanting to say cam phaser now since this is the side with the noise. I have changed them before but have just experienced the noise, never one running like this because of it. Possibly jumped time a little?

My brother's 5.4 has been rough idling and dying at stops and in reverse for a few weeks now. Today it threw a code and he finally had me look at it and it's a P0345 code. I was thinking cam phasers possibly, but I didn't think that would cause a code to throw. Also, all I hear about cam phasers is that it makes the truck sound like a diesel, but his when it's about to die sounds like the engine is about to drop out the bottom of the engine bay. Really rough, REALLY loud knocking, etc... What we should be looking at replacing to get this thing back into shape?

I have a 2006 Ranger XLT 3.0 that is vibrating hard/rough idling, cel is on (solid, not flashing), has trouble accelerating with pedal punched. Will sometimes get a sudden burst when pedal is punched with rpms going up but most of the time no to slow raise of rpms with pedal engaged. Hooked code reader up to it and read ignition coil. Replaced the coil and changed plugs and wires. Truck still not running right. what gives? Is this a fuel pump, cats clogged, cylinder issue?

This problem has been getting worse over the last 2 years. When the car starts it idles fine at about 1000 RPM. As soon as it warms up, it starts to idle rough, between 500 and 750 RPM. It almost quits running. As soon as you give the car some gas it runs just fine. About 3 weeks ago I got a "Engine Lean" check engine light error. I reset the system and have not gotten the error again. Since then I have: changed the MAF cleaned the EGR (made sure it closes completely and ohm out the coils in the actuator) changed the O2 meter on the exhaust manifold cleaned out the throttle body Ohmed out the air idle controller. What I should check next. I was planning to check the fuel pressure in case it is a fuel system problem. It is a 1999 ....

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.

I have APR state I+ and a VWR intake for the last 14 months. My car normally idles at 800 RPM.
In the last few weeks I've noticed it idling a little rough at ~750 RPM.

My 2007 Prius has 127K miles on it and is idling rough, especially noticeable when the car isn't moving.
I've changed the 12V batteries, spark plugs and used cleaner on the throttle body. Car acceleration has improved but fuel economy and the rough idling remain unchanged.
I have an ELM327 and the Torque Pro app and the car is throwing off no codes.

Just noticed the other day the Passat was idling significantly rougher than usual, most of the time it's smooth as butter but not so much lately. It's not rough like a bad misfire, just not very smooth anymore. This could be indicative of the dreaded oil-pump bolt failure rearing it's ugly head (finally)?

Car is idling rough. Mechanic said it might be an oil restriction not getting to a sensor and advancing the timing.

i got a problem with my 96' 2.4 auto cavalier. It idles really rough at idle. I've replaced alternator, battery, idle air control valve, intake, plugs, and the fuel pump in the last year and a half. I've noticed that the rpms will fluctuate between about 625-675 when it's idling rough. About once every 11 seconds the car will rev up for a moment and will idle smooth but then it idle rough again. Every one in a while it will throw trouble code p0200 random multiple cylinder misfire.

I was just at work tonight and went out and started my car for it to warm up (it is -20) and go back inside for about 15 mins, I come out and as I am walking back to my car. I notice tons of exhaust is blowing out from the bank puffing like a steam engine and idling insanely rough with the RPM gauge at about 900 RPM with a EPC code. I immediately shut off the car. Cautiously turn the car back on. Car is idling normally, EPC code is gone, rev it a bit. Everything seems fine.

I have a 1993 Dodge Stealth (3.0 V6 SOHC) that has been idling a little rough, especially when the a/c is on. It was suggested to me that a dirty throttle body could be the cause, so I cleaned it. After I did that it ran great with the exception of idling around 1000 RPM instead of the usual 300, then the next day driving home from work (ran fine on the way TO work) whenever I tried to coast or engine break my engine began to shudder and run really rough! what could be happening?
