Santa FE SM (2001-06) :: Engine Misfire In Cylinder 1 And 4
Apr 26, 2014
2002 Hyundai Santa Fe 2wd 2.7L 175,000 miles
Having misfire in #1 &4, new plugs, new wires, new coils, new cam and crank sensors, cleaned and tested fuel injectors, checked injector signal, checked timing belt.
Swapped around plugs, wires and injectors(keeping same firing order) and the # 1 & 4 will not fire. There is spark to the wires and plugs and gas thru injectors but no detonation.
With plenum and exhaust manifold removed (front only) visually checked valves. Installed new oxygen sensors while exhaust was out. Tested ecu fuses in black relay box in engine compartment.
Engine stars first time ,every time but only runs on 4 cylinders. Check engine light code reads no 4 cylinder 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?

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 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 purchased a 2005 Santa Fe, 4WD, 2.7l..the engine has a miss...the code that came up was "misfire in #2 cylinder"..I checked the coil pack...and the wire harness just crumbled..so I replaced the coil pack...reset the code..and it was good for a couple of days...I got through inspection...today I put on the A/C..and the engine got rough..the check engine light came back on..same code..misfire in #2..I'm thinking the injector or what else could it be? plug? wire?

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.

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?

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?

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.

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

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 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.

As the title says I have plugged a code reader in and it says "cyclinder three misfire". So I pulled the plugs and good god they were nasty. Some having a gap of 80-90 thousandths of an inch. So I figured the plugs were the source of the problem, thus I replaced them but to my dimise the check engine light is still on, and still reading the same ol' "cyclinder three misfire". I have put 350 miles on it in 24 hours of changing it to allow for proper time of the circuit cycling for the light to change but not sure if it takes longer...?
I also went ahead and checked the plug wires resistance when I had the plugs pulled and they ranged from 1.5-2.5k ohms shortest to longest (cylinder 4-1). And if your curious the magic cylinder three was around 2k ohms for however long that wire is, my guess would be 18 inches. Would this be out of tolerance, I know the norm is 10k ohm for every 12 inches or so...?
My next guess would be replacing the power pack or I guess you car guys call it the "ignition coil"...? I will say that the car does run much smoother after replacing the plugs.

I have a 2001 Honda CRV with about 140,000 miles. It is an upstate NY car, so has seen its share of salt and rough winter driving, has a little bit of rust.
I recently brought it in for repairs because it was overheating. It was over the holiday weekend and I had a job interview to get to so I brought it a chain, which was the only open mechanic I could find. They told me there was a coolant leak and replaced the radiator.
The next day, the check engine came on. Cylinder misfire code. I took it back to them and they wouldn't give me a straight answer on what was going on but insist they told me that would happen and it needed more repairs which I had apparently refused. They told me it's probably the spark plugs/wires are old but maybe there's more damage, but basically that they didn't want to deal with it.
So I brought the car to my regular guy. He says, yeah it needs a tune-up. So he replaces the spark plugs and wires etc and gives it back. I drove it for a day and the light came back on. So I brought it back to him again and he refused to do anything. Wouldn't give me some possible causes or explanations, just says come pick it up. Didn't say stop driving it, take it to a dealer, he just reset the check engine light and said its probably fine.
The next time I drove the car, while it was warming up the check engine light was flashing. By the time the engine was warm the light had stopped flashing and was on.

I have a 2001 Mercury Grand Marquis. The check engine light came on and AutoZone diagnosed it as a misfire on Cyl. #4. I changed all the plugs but I do not know how to turn off the light to see if I fixed the problem. How to turn the light off.

Motor missing has 61k. Code reader says # 3 misfire. got new plugs. 2 people say its probably the coil on #3. Its center in the back. Need step by step to replace the coil for #3 and plugs while I've got it apart and where is the best place to get a coil?

I have a 2004 santa fe with a 2.7 v6. I have had a little misfire issue lately. I had a major power loss with a check engine light on it lasted for just a minute before it settled itself out. Had the code pulled at a local parts store. P0301 so I checked the plugs and they looked worn out. I pulled the upper intake and replaced the plugs and wires plus the upper intake gasket. I cleared the code and that seemed to correct the problem. Two days later, same thing happened. The engine seems to be running fine now. I wiggled the wiring harness to the injector and to the coil, no change in the way it runs. I was thinking it could be an injector or a coil pack.

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...

my dad has a 2001 Passat and he recently had his check engine light come on. We had it checked by a guy who owns a tester (snap on) and it comes up with a misfire fault on cyl #2. Wire looks good, I didn't have tools with me so I couldn't take a plug out, but do you think it could be a bad spark plug? Bad coil? Car has 89K on it.
