Santa Fe (CM - 2007-12) :: 2008 - Cylinder 3 Misfire / Vehicle Is Idling Rough
I have a cylinder 3 misfire and the vehicle is idling rough so I took it to the deal because I have a power terrain warranty. They're telling me I'll need a new manifold and plenum, coil pack, plugs, and gasket. Could this be accurate? I don't want to get screwed over...

I have 62,500 on my 08 Santa Fe... never had any engine problems, but today, started the vehicle, drove 1/2 mile in town at 25 mph, turned a corner and the vehicle shuttered and lost driving power. At the same time, the check engine light came on and flashed continuously. I drove 1/2 block (around two corners in town) with the on/off studder and loss of power. I pumped the accelerator just to keep it from killing. As I stopped at the next corner and idled the vehicle regained power. I pulled over and called the dealership service department and they recommended I drive it home (blocks away) and turn the engine off, then try to restart it and if it started drive it 30 miles to dealership.
Did that, engine light came on steady and vehicle had full power. Long and short... the code was P0300 Random CYL Miss Fire Fault (random cylinder miss fire). After scanning the vehicle, test driving it and inspecting it as they do, they could not find a source of the problem or duplicate it. They cleared the code and promised that if it happened again they would credit me the $90 diagnostic fee I paid today for them to find nothing and apply it to a problem they couldn't find. They were willing to try and warranty it even though it is 2,500 over warranty if it had needed parts. Has this cylinder misfire happened to any of you? I've never had a problem like this really go away, so I'm expecting it will show up again. Also, they want to replace the timing belt (at 60K) as a preventative measure. What do you think? Can I wait till 80K?

Santa Fe (CM - 2007-12) :: 2008 2.7l Misfire / Flashing CEL
2008 GLS AWD, 2.7L w/ 66500mi. This happened on my way home from work this AM. Vehicle cold started normally, but I noticed a stumble as I idled out of my parking spot after a 12hr shift. All gauge indications looked OK. A few hundred yards down the road (and deep in the hood no less) I can feel an intermittent vibration/stumble and now I get the *FLASHING* (misfire) check engine light.
5am Sat morning and I'm already on the highway for my ~35mi ride home. The vehicle behaved OK, but you could feel a definite power loss, indicative of not firing on all 6. I hated to, but I had to drive it the whole ~35miles with the flashing CEL. I couldn't smell rich exhaust, nor did I notice any black smoke, etc.
Now I'm SOL. I have no warranty since I'm a subsequent owner (3rd owner of vehicle). Of course I lent out my generic code reader 2yrs ago and never got it back. My garage is currently upside down, tools packed away..etc. We just had a baby a few weeks ago and moved to a new house. Perfect timing.

I am trying to fix my friend's 03 Santa Fe 2.7L with 325K miles on it. Pulled the codes and he has misfire in #3, 6 and a random one. It doesn't do it all the time, and when it does do it he can sometimes shut it off and restart it and it will be fine.
What is the likely culprit causing the misfires and how to test it? He can't just throw parts at it.

I just felt that my 2005 Santa fe shakes when idle in front of a traffic light today, later on the check engine light illuminated. Drove to a Monro shop right way and diagnosis using their professional OBD reader, it turns out that the Cylinder 3 and Cylinder 6 are misfiring according to the OBD scan result.
View 9 RepliesSanta FE SM (2001-06) :: Code P0306 Came Up - Cylinder 6 Misfire
I have a 2004 Santa Fe with the 3.5. Today I started it and the check engine light came on. It was not on before this. (We had a lot of wind and rain from the storm but nothing major.) And seems to be running fine. I went to the auto parts store and they ran a diagnostic and the Code P0306 came up #6 cylinder misfire. They said probably Spark plug, wire or coil for #6, then went to look up code in computer and did not have my truck so they went with Kia or Domestic, which gave different possibilities for a code P0306.
They had me buy some fuel injector cleaner as injector was on the list. The light is still on so I guess the cleaner was not the magic bullet. I spoke to a lady at another auto parts store who is a wiz when it comes to cars and has been around them and fixing them a really long time. She says the Code P0306 is Spark Plug, wire, coil #6. She has a 4cyl Hyundai car not truck and she had the code for her #4 misfire in the past and she started her repair cheapest first, Plugs, wires her code was still there she then changed the coil and that did the trick for her.
I on the other hand can't do this stuff myself. Can't afford the dealer anymore or to have a shop do a tune up AND coil if I don't need all new plugs and wires just a coil as they will charge a lot to do a lot all. And it may not need it or even be any of those things. I also suspect the dealer and shops will want to still hook up their computers to do an costly diagnostic because the light is on, even though I know the parts store already came up with a code P0306 twice. Spoke to the dealer on the phone and he already basically said they would want to do that first for $100 plus the cost of repair.
I brought the truck new. It now has 91,500 miles on it and the dealer has already done two tuneups on it in that time, Plugs and wires. I hear it probably shouldn't have even needed these tuneups in this amount of millage? So the last one was probably about 2 years ago and a few thousand miles maybe a guess 10,000-20,000 miles ago. Do you think a plug and wire would be bad already in that few miles?
Santa FE SM (2001-06) :: CEL Came Up With A Code P0303 - Cylinder 3 Misfire
I got a check engine light. I went to Auto zone to get it read & they came up with a P0303 - Cylinder 3 misfire. Since I bought the vehicle a couple of months ago, I don't know when the plugs were last changed, so I decided to change them. However . . .
Is there a secret to getting the plug boots & wires out of the hole and off the plug without wrecking the wires?
Santa FE SM (2001-06) :: 2002 - Code P0302 / Misfire On Cylinder 2
I have a 2002 Santa Fe 4 cyl that is giving me a problem that I could use some advice on tracking down & fixing . First & most important is a code P0302 # 2 Cyl misfire. How to check the ignition coil pack , injector ,& wire for this cylinder in home garage with normal tools & meter . Is there a you tube displaying how to do this step by step ?
The other problem which I don't have the code for at this time is that some part of the exhaust is not getting warm enough & this also put's the check engine light on . Will get back on this one when I solve the main problem Misfire.
Santa FE SM (2001-06) :: Burned Out Plug Wire - Number 4 Cylinder Misfire
I've had the plug wire for my #4 cylinder burn out twice in the last 6 months. The car started running like crap and threw a CEL, the code was for a number #4 cylinder misfire. When I pulled the wire it has obvious signs of being burned out, like white powder and burn spots near the base of the wire where it goes over the plug. The plug and coil both look normal. No issues with the other cylinders. What could cause it?
This is on my '05 Santa Fe, 2.7l, FWD auto, with 180k miles
Santa FE SM (2001-06) :: Engine Light Come On With Code P0302 Cylinder 2 Misfire
I have a 2005 Santa Fe with the 3.5 with 112000 miles on it. I had the engine light come on with the code P0302 cyl #2 misfire, I got spark plugs, plug wires to do a tune up on it. I changed all of it and got it back together, started it up and it still had a miss to it. I then took the front spark plugs out and did a compression test on it. #2 was at 85, #4 was at 120, and #6 was at 160. I couldn't check the back cyls because I had already put the intake back on. I then did a wet test, and all the cyls came up to 160. So this tell me that the piston rings are bad in #2 and going bad in #4. I have kept all the oil changes up and up to this point I haven't had any trouble with it. Having this problem with there 3.5?

We got our latest Santa Fe computer email and it warned of an engine fault. The car itself was not flashing any warnings though. Took it to the dealer and they said OBD was throwing a P0303 cylinder 3 misfire code. They shifted the ignition coil, and replaced the injector and seal before resetting the code. They had the car for 3 days though. Car was not running rough or anything else you would expect from this type of issue. Still trying to figure out why we got the email with no indication of trouble from the car itself.

I have an 07 kia rio, I had a misfire in the 3rd ignition cylinder. When I opened it it had oil in it. So I cleaned it out and put a new spark plug in it and change to a thicker oil. A few hour later wet to drive it and after five minute the car shut down. When I was able to get it to turn on, it started to knock. I got it check and said misfire in the 1st cylinder, So I changed out all the ignition coil one by one it didn't work till I got to the last one, the knock went away for a few minutes then came back. So I put the originals back it and the knock is gone but it still misfiring with the check engine light flashing or staying light.

2005 3.5L FWD. 5 days ago I left the house, the engine was running smooth at idle but having hiccups when accelerating. Check engine light went on when accelerating but going off at idle. Turned around at the first stop light, parked the car home and pulled code P0302 misfire on #2 . Figured it's most likely the coil, was going to order one next day but to my surprise, no more check engine light next day and engine has been running smooth since then. Probably drove 100 miles since with no issues. I have 6 spark plugs waiting to be replaced but it's too cold to do it right now unless it's an emergency. Car has 105k miles now, spark plugs were changed at 63k. Was this just a fluke and P0302 will probably not come back or should I not risk it and just go ahead and replace the coil? If I end up replacing the coil, should I do one coil or all three?

I own the 2014 Santa fe turbo 2.0 litre limited which has 4000 km on it. Within 210 km the engine light came on 3 times. I took it into the shop and they ran a code of P0303 which is a misfire, they changed the coils #2 and #3 and cleared the code. The second time it showed the same code but the shop said it was in the history so that is why the same code came up again. They ran an update ECM? and all was good. Now the 3rd time they tell me no code has come up and can't do anything about the engine (they cleared it) but it was like chasing ghosts. My vehicle runs great so not sure why I am constantly having this issue.
