Santa FE SM (2001-06) :: Code P0302 Misfire In Cylinder 2
Aug 17, 2016
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 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 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 have a 2010 accent GL manual sedan. It has 104,962 KM on it, the warranty expired December 18, 2015. Since February this car has become a frustrating money pit. Being in the dealership constantly for repairs, then within a week something else 'happens' and back it goes. Spent almost $5000 in 4 months on repairs. Decided that's enough and will do majority of repairs myself.
Yesterday while drive on the highway I had a sudden loss of power and a check engine light came on. My scanner which has become a standard item in my glove box indicated a misfire on cylinder 2 - P0302. I limped the car home, in 3rd gear I was having a hard time staying above 2000rpm at 60km/h. at lights I had to use hand brake so I could keep my foot on accelerator, revs were dropping below 300.
Today I replaced all the plugs (all 4 were still in good or better condition, #2 showed signs of a slightly rich burn and #3 a slightly lean burn), replaced all coil boots (no cracks, no burns, and still pliable), removed and cleaned all the injectors. Error code P0302 persists.

Getting error code p0302, misfire in 2, pulled the plug and had oil on the treads and on the lower part. My guess is the valve cover gasket, but I'm not 100 percent sure.

I have a 1995 ford ranger 2.3 L dual coil packs new plugs, wires, coil packs, tps, idle air sensor, internal temp sensor, and a replaced mass air flow sensor from wrecker. That all said my one son missed a plug when i replaced it , it had no tip left on it , but since then i now have a misfire in cylinder 2 where the olther plug was found and replaced ...
Gap for plugs are .44
Used the wrecker maf to see if it would clear a p0113 which it did. I am stumped on why at approx. 30 minutes of driving that the cel will flash then set a p0302, no other codes no fuel smell. rechecked plugs all are clean haven't been able to check fuel pressure yet, and i out a can of seafoam in the tank to see if it clear out injectors.
Besides all, I will check injector to see if I hear anything but I'm stumped. Also we have to have an emission test so is it best to fail the test and will it show me what I'm missing.

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 Camry, 2.4 with 155k miles.
This morning I was going to work and was making a lane change and hit the accelerator quite aggressively. Suddenly my engine started to run really rough and shook the car and the check engine light started flashing.
I checked the engine code and its giving me a P0302 Cylinder 2 Misfire warning.
I have read that there can be various reasons but I figured since this problem is consistent its not a vacuum issue? Could it just be a bad plug? I don't have the tools to fix it, I am going to get them soon to pull the plugs and inspect then, and will replace them anyway since I don't think they have ever been replaced.

Check engine code (P0302). I have a 2007 GS 350 with 116k miles that was driving perfect until this week. My check engine light was initially blinking but is now on solid along with the check VSC light. My question is: of the 6 cylinders (3 on the left and 3 on the right when facing the engine) which one is cylinder 2?

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.

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.

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 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 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.

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.

I recently changed my spark plugs + coil packs in my 01 1.8T because it read a couple cylinder misfire codes. Drove it for a few days out of curiosity plugged the code reader in again and it's still reading misfire codes. What could the issue be still?

I have a 2005 Jetta 2.0 BEV GLS. I got a code P0302 for misfire on cylinder 2. I am pretty sure it's the Ignition coil. I live in Canada and my autoparts store only has BWD brand. I have read this is a crappy brand.

2009 Accent, 1.6L 154,xxx Cylinder two misfire. Engine was rebuilt due to timing belt. Twice. Second time I did it. Replaced plugs, coil packs, all gaskets, (everything new in the head) did a smoke test, compression test 180 psi across all four, used a noid light for coil packs (good) did it at the injectors 1,3,4 did good, but 2 came on then went off. Check resistance and it shows good, replaced injector anyway and the connecter. Still doesn't work. Checked powers and grounds at the rail, good. Good solid voltage. I hooked up a scan tool and tried to shut injector 2 off, no change in RPM or vibration. Scan tool worked for 1,3,4. Used another PCM, still misfire in two. Even jumped a wire from PCM control and 15A inj fuse for the 12V constant (bypassed the harness) and still doesn't work. Also have knock sensor code, just two codes.
