Sonata NF (2006-10) :: Rough Idle - Codes For Power Steering Pressure Sensor
My car has had a rough idle (no MIL). Scanned for codes and got the following:
P0552 - Power Steering Pressure Sensor - Low
P0553 - Power Steering Pressure Sensor - High
I'm picking up the part at the dealer this afternoon. I printed out a diagram of the component location, and it looks to be easily accessible.
Sonata NF (2006-10) :: 2007 - Rough Idle And Bad Acceleration But No CEL
2007 Sonata V6. He's spent many hours and a good chunk of change at the dealership trying to get it fixed and nothing has worked yet. They honestly have no clue whats wrong which kinda scares me.
First off here is his problem. Occasionally when he starts the car it will idle very rough and struggles to accelerate to 30-40mph. When this happens he pulls over and shuts the car off for a few minutes then it will run fine again. When all of this happens there is no CEL or any light at all that flashes or comes on the dash.
Here is a list of things that have been replaced
Fuel pump
Throttle position sensor
Crank sensor
Plugs, wires and coil pack
Sonata NF (2006-10) :: 2007 - Rough Idle And Even Worse After Gas Fill Up
So my sonata 2.4L has been freaking me out lately. Once it has been driven and warmed up good, it starts to idle rough at rest at lights and in traffic. Now the crazy thing is it idles even more rough if I switch it into neutral during those stops. One more thing is it idles the worst after I fill up with gas and get stopped at lights.
So what I have done:
Cleaned the MAF sensor with MAF spray
Changed spark plugs (I4 so it comes with coils not plugs)
Put Lucas Gas treatment in
So I'm getting no check engine light. So all I can think of is fuel filter. Or some other sensor. I mean I know it could be a coil so that would be the next thing I check. What this could be?
Camry :: 2.4 Engine - Misfire Codes And Rough Idle
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 RepliesFord F-150 (2004-2008) :: Rough Idle / P0012 - Misfire Codes Associated With Bank 1 And Cylinder 3
5.4 3v. my last few weeks have not made me a fan. Here are the details:
I bought a 2008 F150 XL 5.4 3v with a cam phaser knock. Have done other timing jobs in past with no trouble so I was not too afraid to tackle this one. famous last words...opened the motor (shout out to the passenger side valve cover and its designer here) and found semi damaged roller follower on driver side. Worn cam lobe on the corresponding lobe and a loose chain on passenger side. proceeded to :
Change all timing components: phasers, chains, tensioners crank sprocket, all applicable bolts and BOTH cams as well as all lash adjusters and roller followers. most looked fine in fact all really did with a bit of wear on a few roller followers but only one bad one. engine didn't look to bad pretty clean.
Double and triple checked my timing chains and it was spot on. dark link on spot on crank, two dark links on the L and R dead on. put it back together. oh yes, changed all plugs with motorcraft ones, didn't even break one. did not change vct solenoids because I falsely assumed I could change the later easily if needed. they looked ok. screens intact etc... silly me for not realizing how kind Ford was in 2007 and later to necessitate removal of valve cover. I was reading a previous one on the how tos and assumed later models would be the same since it was the same sensor...
Cranked truck ran great. I mean perfect. sounded perfect. ran like a scalded cat. till it got to hot idle then it started doing its thing. rattle shake till you revved it. ran fine just wouldn't hot idle fine especially in reverse or under slight load. replaced driver side vct since ford only had one and I started on the easy side ordered the other one waiting for it. seemed to improve dramatically meanwhile I am driving this truck to test it. I drove it to work 50 miles each way and it ran great.
After a few trips it popped the P0420 light, seemed to run ok, cleared it watched it wouldn't come back. O2 sensor did seem to imply a bad cat on bank 1 since it seemed sensor two was mimicking sensor one and not staying stead like the other bank. still ran fine,
So I decided to check back pressure on the cat. I pulled sensor one out of bank one (really a joyously tight squeeze in there) hooked up my gauge and got 0 back pressure. revved it and all nothing. hooked sensor back up pulled truck out of shop and it commenced to running like crap. I mean bad. running worse than before I got it. Popping P0012 code continuously, and tons of misfire codes associated with bank 1 ..cyl 3 etc.. I tried swapping coils, pulled coils and checked spark with a tester and firing away looks like tons of good spark.
Now the weird part is : looks like bank one is dead. I can unhook any coil pack and/or injector and it runs the same and sounds like it is missing. if I unhook one off of bank 2 it almost dies or does. so bank 2 seems to be running fine. it will start and run but sounds like it missing sets flashing check engine light and backfires and stalls like crazy. I even second guessed my pressure gauge and unhooked exhaust manifold from pipe and it sounds even prettier when it backfires out of there but no change. I pulled cam sensors and cleaned it again and even tried swapping them since they looked identical but no change so I put them back.
Now I can only surmise that I am out of time somehow? or I have a gremlin perhaps? I like working on cars (usually) but this one is getting old. how do I verify what is wrong. if it is timing related how do I verify that now definitively once my marks moved I really cant figure out how to tell if it is in time? Since it has all new parts and they all ran beautifully till now. could it possibly be the vct solenoid doing all this? I plan on changing it when it comes in but surely it cant cause this many problems.. I unhooked it no change, and it does it at a cold idle and any rpm. really runs worse at idle but bad at any rpm.

View 1 RepliesSonata NF (2006-10) :: Idle Seems To Almost Misfire When AC Is On
When at idle and it seems to either only do it or is worst when the ac is on. the idle seems to almost misfire. Usually its only for a couple seconds less then a min. I have had my odb2 hooked up to it and its about a 25-50rpm drop but it keeps doing over the course of a few seconds. It hasn't stalled doing it yet and its done it for years! however today at the drive thru it was quite aggressive. Usually I give it gas and its not as bad or completely stops, sometimes is doesn't work at all. This time I just let it keep doing it hoping a CEL would come due to it being more aggressive then ever but it just evened its self out after about 30 seconds. Almost feels like there is a mild performance cam in the car....
View 9 RepliesSonata NF (2006-10) :: Misfire On Cylinder 3 And 6 - Running Rough When Slow Down The Car
When I'm driving and get above 50-60 I will get the Check Engine Light. Check the codes It shows 6 ---300, 303, 306, 300, 303, 306. When I slow the car down it is running rough, almost like it has a miss.
I reset the computer while this is going on and the engine smooths out and it runs correctly until I keep my pedal down and then it kicks the exact same errors.
Here's strange part number one: Once I get down to about a gallon or two of gas in the car everything seems to run fine. I have plenty of power, no codes and the car runs fantastic!
Strange part number 2: Very occasionally When I get in the car in the morning to go to work, the car is a bit difficult to start. When it finally kicks over, it is immediately running rough. resetting the computer with the engine running does not seem to stop the rough running. If I turn off the engine and let the car set for a bit it will start and run fine, with the exception of the first problem mentioned in this thread. There is no code while it is running rough, but when the Light kicks on as per the first issue mentioned, I have an additional code -- 335. This car has been excellent up until the last few months when this issue developed.
Lexus GS 2006-11 :: GS300 Rough Idle / Misfire On Cylinder 2
I bought a 2005 3rd gen about 8 weeks ago and I love it except for one problem, a really bad idle/vibration through the cabin when cold starting, it improves when the engine is warm but is still noticeable.
It went back to the dealer where I got it and they gave it a full service, new plugs, oils and filters and replaced the transmission oil too after the check vsc and engine management lights came on.
The codes pulled showed a misfire on cylinder 2, the dealer said the service would cure all and sure enough no more vsc lights but the rough idle and vibration are persistent.
The car has only 78000 miles and I'm pretty certain a Lexus isn't supposed to behave like this.
Elantra HD (2006-10) :: Rough Idle When Cold / Slight Misfire
My moms has a 2010 Elantra with 30,000kms on the clock, and we have noticed since new when the vehicle is started cold in the morning it seems to run rough for about 30-60 seconds then stabilizes.
It's almost like it has a slight misfire, or slight fuel flooded from sitting overnight. Now if course we have taken it to the dealership twice for this issue and dropped it off overnight for a cold start, and both times they cannot re-produce the problem.......surprise.
Accent MC (2006-11) :: CEL Flashing / Rough Idle - Cylinder 1 Misfire
I did not get the specific cel code but its what the guy told me at autozone.
Long story short. Washed engine, let sit for about 30 mins. Car started with flashing CEL and was "puttering" and very rough idle. Drove home took intake off and replace with stock, took spark plugs out and they were not wet. Then let it sit for about 15 mins. Started just fine. No CEL at all.
The accent saved the CEL and the guy told me that Cylinder 1 had a misfire.
My question is, should I do anything now even though the car seems to be running ok?

After scouring through hundreds of threads on this forum (which is Awesome, BTW), it seems as if this misfire / rough idle thing is fairly common (which is scary!!). CEL is on steady. Had the codes pulled; P0301, P0302, P0303. At the recommendation of the mechanic, I had the plugs replaced...no improvement. He then replaced the ignition coils...no improvement. Just finished replacing the MAP sensor. This actually had a VERY temporary positive effect. However, after about 5 miles of driving, the misfiring returned. Took the car to the Hyundai dealership, and they acted as if they didn't want to fool with it. They referred me to a couple of local repair shops...????

2006 F53 (motorhome) with 6.8L V10. Rcently noticed rough idle and midrange (under load) mis fire. Had codes on 2 coils. Replaced coils and put new spark plugs in. Did not improve and now detecting mild back fire.
Just completed compression test. 1=207psi, 2=200, 3=210, 4=190, 5=197, 6=200, 7=200, 8=170, 9=202, 10=208.
put some oil in #8 and retested at 225!
Other observations on #8. Engine has ticking noise chased with stethoscope to #8. THE new plug with 200miles, insulator going to electrode tip and everything inside combustion chamber is black. All 9 other plugs still look new out of box.
With the ticking noise I was suspecting valve but the compression test with oil jumped way up.

View 4 RepliesSonata NF (2006-10) :: Oil Pressure Light At Idle And CEL With Codes P0011 / P0051
I recently bought a 08 Sonata V6, with 94K mileage. The oil pressure light comes on when the engine is idle (around 700-800 rpm). The seller told me that this problem started a few months ago, but the car has not been used much since then. He also said that he has changed the oil after that, but the problem still persists.
The engine light has shown up more recently, like in a week or two. I took the car to a mechanic and he could not guess what the problem might be. But he gave me the error codes: P0011, and P0051. There are no other obvious symptoms (e.g. oil leakage, low oil level, unusual sound from the engine).
I could not find any thread regarding both of these issues (Oil Pressure, and the error codes) together. Any connection between these two?
So far, I have realized that the oil pressure can be due to a bad sensor, and P0011 has something to do with CVVT, and Oil Control Valve (OCV). But I would like to make sure I don't just waste money by replacing the sensor and OCV.

Sonata NF (2006-10) :: Very Rough Idle When In Gear
I have a 2006 Hyundia Sonata. I idles really bad like you pulled 5 of the six plug wires off when you put it in gear. Once you start moving a couple miles an hour it is fine. It is also perfect in park or neutral, not a hint of a problem. Put it in drive or reverse and it almost stalls.
