Sonata NF (2006-10) :: Surging And Cutting Out Once Warmed Up - P0304 Code
I was on my drive in to work Wednesday and the car once warmed up started surging and cutting out. I got it to work and home again and hooked up my code reader and came up with P0304 meaning misfire in number 4 cylinder.
View 2 RepliesSubaru :: 2006 - Fixing CEL Code P0304?
2006 Subaru Forester X 2.5L AT non-turbo
I changed the oil and oil filter; replaced the air filter (Fram), and replaced the alternator and a/c belts. I also got a full tank of gas at Sam's Club, I was nearly empty. I've gotten gas plenty of times there, before.
Next day, the CEL comes on. It's a P0304 code. (Cruise control light is flashing, too.) Engine stumbles and runs rough when cold; idles fine when warm, runs OK, but not the same, when warm. CEL is steady, which is "not bad" but I can make it flash if I hit the accelerator while the engine is cold. Resetting the computer by disconnecting the hot battery terminal didn't work; CEL came on again two days later and symptoms remained.
I buy some MAF cleaner (CRC) and use it; MAF was pretty dirty on the upstream side, actually.
I'm going to change the plugs and wires (they need it, anyway) and I've ordered a new ignition coil, which I'll also switch out.
I've also ordered the gasket for the throttle body, which I'll take apart and clean once that comes in. Last step is to order replacement O2 sensors.
I'm 99% certain there's nothing wrong with the engine, in terms of rings, valves, pistons, etc. I think I'm covering all the bases in addressing this myself. I'm on a limited budget so I'm doing all the labor myself and ordering non-OEM parts on-line, after researching to make sure the parts have a good reputations, fit, etc. (Yes, that's all a big FU to Subaru service for being over-priced but besides being relatively poor I also enjoy doing this stuff.)
Sonata NF (2006-10) :: Engine Malfunction Light Codes P0106 And P0304
2010 Sonata GL Sport at 122,000 kms (75,800 miles)
Engine Malfunction Light came on solid. Using ODBII reader, my Honda mechanic friend read the codes to be
P0106 Current, Pending, Permanent - Faulty Manifold Absolute Pressure sensor
P0304 Pending - Cylinder 4 Misfire Detected
He replaced MAP sensor and Coil pack. But the Engine Light remains on solid. Now its only giving code P0106 which kind of points back to MAP sensor.
Spark plugs has never been replaced so I've been suggesting to replace it anyways proactively.
Questions:
1. What else may be causing the Engine Light?
2. When do Spark Plugs typically get replaced?
Sonata NF (2006-10) :: Popping Noise In The Suspension
My 2006 sonata 85,XXXX miles on the car and after putting the new rims on the car. I am feeling a bit of popping from my power steering at low speeds when turning. The Power steering has been squeaking for quite some time. I have never changed out the power steering fluid and was wondering if this could be the cause!
View 7 RepliesSonata NF (2006-10) :: Creaking And Popping Sound While Driving
Just replaced the front struts last week and the upper control arms this morning. After putting everything back together I drove her around the block and noticed a horrible popping and squeaking like something was loose. I quickly limped her home and double checked that everything went back on properly and was tight. Car is the V6 with eibach's and about 103,000 miles I have drain and filled the tranny every 30-40k.
What this sound might be? It goes away once I am above about 10-15 mph and sounds like it is coming from the center underside of the car. I will also try to get a video of the sound while I am driving.

Sonata NF (2006-10) :: Cannot Raise Window - Popping Noise
So today, when I rolled down my passenger window (2007 Sonata GLS) to talk to someone, I heard a popping sound and the window refused to roll back up. I got the car home and started tearing into the door panel (okay, not literally). By viewing different threads here, I have the door panel off, outside handle is off, all screws loosened (including the 3 for the door latch) and am trying to get the inner sheet metal panel off.
From everything I've read, you need to roll the window up the whole way in order to get the inner panel off; however I cannot get the window up the whole way! By lifting up on it, I have it about 2/3 raised, but it won't budge any more. I have been able to see that the window cable is broken (which explains why the window won't raise), but am at a loss on how to proceed. I'm leery of trying to force the window up any more. I'm tempted to try to pry the inner panel back enough to get the two bolts holding the window loose, but don't want to force *that* either.
So, how to get the window all the way up? And/or the inner door panel off?
Sonata NF (2006-10) :: Popping Noise From Driver Side Near The Door
We have a 2008 NF, and have been experiencing popping noises from the drivers side near the door. Especially when it's been colder out, but in general.
The tie-rod ends, ball joints, and the struts have been replaced. The question is: What we is it likely to be?
The car has ~100k on it, so it was not really to surprising that those items would need to be replaced.
However, since I didn't have time to do it, we had someone else do the eval and work.
Are there any typical issues that stand out with the NF Sonata that would cause this based on what I've told you all?
It's a great car, but this is driving us nuts.
Sonata NF (2006-10) :: 2007 3.3L - Popping Sound When Turning Right While Braking
I'm experiencing a really annoying issue with my 2007 3.3L sonata. Whenever I am making a right turn (with the breaks applied), I hear a knocking or "popping" sound from the driver's side front end. It's not a single "pop", but multiple "pop"..."pop"..."pop". The noise does not occur when making a right turn without the breaks applied, not does it happen when making left turns. Also, during a right turn, if I release the breaks, the sound will immediately stop. The car only has 64k KM (about 40k miles).

I've been hearing a popping noise occasional when reversing into a parking spot for about a year no, its like 3-8 pops each time. I looked at the CV joints and the rubber hosing is intact. I am pretty sure this particular noise now is not ball joints squeaking.
How long can I let this slide without replacing. Is the CV joint sold as one whole piece?
BTW I'm checking out the 2013 Sante-Fe....

Accent MC (2006-11) :: 2009 - Low Purge Flow Error Code Popping Up
Not too terribly long ago I got assistance on identifying and fixing an engine misfire on my 2009 Accent. I assumed was directly connected has cropped up again - a P0497 Low Purge Flow error has come up on the car.
We recently replaced the purge flow valve, and everything seems to be running fine - there is no visible cause for the error, and I've even tried making sure I get the fuel cap as tight as possible.
The code is not popping up constantly - this is only the second time it's come up since the misfire was fixed(without obvious symptoms I always clear a code once just to make sure it wasn't a computer glitch), and the first time it popped up on it's own was the day after I fixed the misfire. Need to know what to check to find out what's wrong and, of course, how much priority I should place on fixing this issue.
Accent LC (2000-05) :: After Every Fill Up CEL Code P0304 Came On
2004 Accent - auto. - 100K miles
CEL for code P0304. I thought I had it solved but now it comes on after every fuel fill-up. Its happened at least 5 times or more. I know what the code means (ign. misfire #4 cyl.).
I read and checked what affects the code but this one has me baffled. I thought at first it is the evap. canister but the car takes a fuel fill-up without any trouble and it is not hard to pump it all in and does not give me the code. If I put a bottle of STP gas treatment in the tank it clears the code after about 40 miles driving but it doesn't explain why it sets off the CEL on every fill-up. I also thought I may have sediment in the tank and the fill-up is stirring it up but I have filled her up and various capacities. Also, several weeks ago I got the CEL code P0441 for the purge control valve. I replaced it, cleared the CEL and it never came back on. Fuel filter has never been replaced because it is built into the fuel pump assembly.
Overall drivability and MPG's are not affected.
Toyota - Tacoma :: 2004 V6 - P0304 Code Won't Go Away

Have '01 SE. yesterday I got a misfire in cylinder 4 (code P0304) the service light blinked on and off 3 to 4 times than stayed solid. changed plugs and boots about 1 to 2 months ago, didn't change coils and they r not in the best shape but didn't have money to replace at time. So I replaced the coil for #4 and it still runs rough with code, plug has some ware but looks fine.
View 1 RepliesS-10 :: 98 Chevy ODB Error Code P0304 / Cylinder 4 Misfire
I left my chevy s-10 truck sitting over the christmas (23/24/25) and it was really cold outside and when i got back i started getting a P0304 (Cylinder 4 Misfire). I replaced the spark plugs and spark plug wires. May be the cold would cause this to happen? I think I've noticed the trucks fuels efficiency drop over the past month). May be the fuel injector(s)? Is the s-10 TBI or does it have fuel injectors for each cylinder?
View 8 RepliesCamry :: 2002 - P0304 Code / Misfire Occurring
We just bought a 2002 Camry with 72,000 miles 2 months ago. It now has 74,000 and while on vacation the CEL came on. I took it to a mechanic who got the code P-0304 off the computer. He swapped the number 4 ign. coil pack with the number 3 cylinder. The CEL light went off and I was able to drive the 300 miles home. The next day the CEL started again, but this time it's flashing. I changed the spark plug, it looked good, and still have the CEL on with the P-0304 code.
I've inspected the wiring to the number 4 ign. coil pack and it looks good. I'm thinking the next thing would be the fuel injector.
The car runs great, you'd never know by driving it that there is a misfire occurring. If it's not the wiring or fuel injector what should I check for next?

View 2 RepliesPassat (B6) :: Cooling Fan Won't Shut Off - Code P0304 / P0864
So, over the past day and a half my beloved B6 has been putting me through the wringer... Sunday morning I fire it up, drive to church, turn the car off and everything is fine. Church is over, I drive home, turn the car off and my cooling fan keeps running... I go inside and check again in about 15 minutes hoping it had shut off after 2 minutes or so, but nope, still running. So, in order not to kill my battery, I disconnect it. I let it sit for a few hours and went back out hoping that leaving the battery disconnected would reset something, but as soon as terminal touched the lug, the fan kicked on again.
Now, for the electrical issues that have come with this problem... Whenever I hook the battery back up, a few things can (and usually do) happen. The steering and traction assists don't work, the parking brake malfunctions, the transmission shifts HARD (if feels like somebody is rear-ending me), occasionally the transmission just stays in 3rd gear, and all of the PRNDS emblems in the dash readout are highlighted as if they're all in gear at the same time. Now, cut the car off and back on a few times and most of these issues go away, but other times I've got to fight it a while and disconnect/reconnect the battery for everything to fix itself. I popped my scanner on it, because it's throwing a CEL as well, and aside from the P0304 misfire code (stupid intake valve crud...), I'm occasionally getting P0864 - TCM Communication Circuit Range/Performance. Not sure what's going on, but it seems like my car is self-destructing...
