Santa FE SM (2001-06) :: Burned Out Plug Wire - Number 4 Cylinder Misfire
Nov 12, 2015
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

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.

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 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?

My dad's 97 dodge neon is showing a misfire in the number 4 cylinder. He replaced the spark plug but still getting that code and engine not running smooth. What other things could cause this? Engine has about 130,000 miles on it, had been running fine.

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?

1999 ranger 155k 3.0 flex fuel. 304 is misfire in cyl number 4... I replaced the plugs and wires and checked the coil. the compression in cyl 2, 4, 5, 6 and got 80-90 psi so they are consistent but consistently bad right, it may be my compression tester.
The #4 plug was spotless after running 5 min, the #5 plug had some black on it already. Its hard to tell but it seems I had fuel residue on the plugs on cyl 5 and 6 but none on 4? Whats next pulling the intake to get to the injector?

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?

The electrical connector to the camshaft sensor on my 2003 Santa Fe 2.4 engine has disintegrated so badly (I think due to engine heat) that I need to find a replacement. I have already repaired this connector several times with superglue and it has now reached the point where it is just no longer repairable. (same thing happen to a person of this forum back in 2008)
However, this connector cannot be purchased on it's own, according to the hyundai agent, we need to replace the entire wiring harness.

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 am getting a cylinder 5 misfire and this has been a "on again off again" situation since last August. I took it around to a few places and the general solution was to get new spark plugs. After doing a bit more research I was advised to change the coil cover. I did that and it fixed the problem. Then about 4 months later the light came on again. I happened to change the air filter and the light went off. I though great, problem solved! not so much, when i went to the mountains the other day the light came back on. I did my research again and I have decided to get the plugs changed. Its a 2005 f150 with 94,500 miles on it.
I am told its time to change them regardless. I started calling around and getting quotes and have been told by multiple shops that ford made the plugs in my truck in a bad way. They have been telling me to change them and breaking them is a 50/50 shot. THEN, when they quote me they charge a rate to replace them plus the plugs themself. If they happen to break one then the customer pays for the new one. Do the plugs would really break that easy and should I plan on replacing some of them?

A cab light (OEM) has burned out. I'd like to replace it. What style/part number bulbs are used?
The closest tangential reference I can find is to 194, with additional references to 168 and 912. A Google Image Search of makes it seem like I'm getting warmer.
