Yes to the previous two answers also check crank sensor and flywheel there could be something preventing the sensor from correctly reading the flywheel.

Is there visible spark going to cyls 1 and 3? Is It equipped with variable timing? Are the injectors getting fired at their connectors? If all checks out...Perform a running compression test on these cyls to see if there are compression issues caused by variable valve timing solenoids

    Pulled the injectors and tested them they are fireing and the are getting fuel. I also replaced the fuel pressure regulator. This is not a variable timed engine

    If you have compression spark and fuel....It has to work. I would still do,a running compression test to verify compression is good running and not lifters collapsing at higher speeds

  • Eric frain Apr 11, 2015

    I also pulled the head to check for bent valves. Check the timing like 50 times replaced crank and can sensors. Hooked my snap on scanner to the car no codes and nothing on displayed data that's poping out at me

    Hmmm..You certainly have all bases covered. With the valve cover removed and engine cranking is there good rocker arm valve movement?

  • Eric frain Apr 11, 2015

    Yes this is why I'm at a loss. I know its something I'm missing. It sames funny that both the cylinder that are missing is the ones that the coils are not on they have wires going to them from the coils but I also replaced the wires as well

    Is there visible spark from those wires to the plugs. Are the plugs to those cys getting fuel fouled? They should be if they are not being fired.

SOURCE: 2001 Hyundai Santa Fe Ignition coils & EGR Valve

Well I went ahead and took a go at changing the coils, plugs and wires yesterday. It literally took maybe 15 minutes and my hands didn't even get dirty. This is something that the auto place wanted to charge me 650 to do. I spent 200 on parts. I didn't realize the coils were the things sitting on top of the spark plugs. I think my 4 year old could've done it. All I had to do was unbolt the coils detach the wires and then replace. It was too simple.

If you live in the US, take it to qany Auto Zone store and thy will read the codes off for you, I would suspect any right thinking competitor would do the same, check if you don't have one near by.

Hope this is of some help.

Cylinder 3 misfire on 2001 Hyundai Santa Fe


sometimes the fuel injector can be out of range but this would give a trouble code.
then check spark plug to see if it is wet or fouled.
check plug wire for external sparks.
last check the coil pack.

04 santa fe 2.4 has code po301b misfire no.1 cyl.also starts hard warm. I own an automotive shop struggling with this fix. any suggestions GB


OK the usual checks are plug (compare plug with adjacent plugs to detect any specific difference), pressure test the cylinders (this checks on compression efficiency - poor compression on this cylinder as compared to the rest indicates worn valve seats or piston rings) HT socket (look for sign of cracks or charge penetration of insulation through to the cylinder head) , HT lead resistance (should all be similar for all leads) and then the coil(s). If coils are shared then cylinders 1 and 4 share the same coil. If you disconnect the HT leads to the '1 + 4 coil' and try start the engine you should see a spark jump between the two coil terminals indicating healthy cam sensor function and coil condition. Next I would look at injector function, Simply swap over injectors 1 and 2. If the problem error code now becomes P0302 you now know it is the injector. When doing this job look at condition of sealing injector o rings, sometimes air can enter when these rings are not seated correctly. Check that the inlet manifold bolts are to the correct torque. If you suspect the injector back flush it to clear clear any obstruction. Maybe remove the fuel pressure regulator and flush the fuel rail.

I keep getting a misfire in cyclinder 4? the car also now will not accelerate past 3000 rpm's i pulled the plugs and only 4 looks like its not firing i replaced it last week... there is no oil in the water...


The very first thing that you should do next is to take a compression reading especially the #4 cylinder, to determine if the mis-fire is caused by a mechanical problem or an electrical problem. If you are looking for an electrical problem when the problem is actually a mechanical one, you could wind up wasting a lot of money and time.

A mechanical problem that would cause a low compression mis-fire in the engine could be a burnt or bent intake or exhaust valve, a worn out or broken piston or compression ring, or even a warped cylinder head.

An electrical mis-fire would most likely be caused by a faulty ignition coil, a worn out or cracked distributor cap, worn out ignition wires, worn out spark plugs, or a faulty fuel injector.

2002 hyundai santa fe 2.7 multi misfire number 2and 5 cylinders


OK IS THERE IS ACTUALLY A mis-FIRE THIS VEHICLE SHOULD BE SHAKING DURING IDLE AND ACCELERATION IF IT IS, here is what you do get a noid light this used to check injector pulse. This vehicle will set a misfire code if injector is not functioning efficiently or bad. A noid light is like a test light bulb can be bought at almost any auto store.SART UP VEHICLE AND DISCONNECT THE INJECTOR WIRE TO THE CYLINDER THAT'S mis-FIRING AND CONNECT noid LIKE TO ELECTRICAL PLUG. DO THIS ONE CYLINDER AT A TIME. The nod light should have a steady flickering light/consistent pattern of flickering. If there is Gap/irratic flickering or no flickering BINGO you have found your problem. NO FLICKERING= bad/broken injector wire if not broken BAD COMPUTER/ECU. IF THE FLICKERING IS CONSISTENT /GOOD = BAD INJECTOR..replace injector and solve the misfire problem. However is all the components tested are ALL GOOD. Then the only other SOURCE for a mis-fire is the camshaft sensor that provides reference for injector pulse and the crankshaft sensor provide reference for Spark pulse. JUST ON A LAST NOTE: make sure all oils are getting electrical power to them. Good Luck I know this is alot of info at once. Contact me if you need more help. Thanks fr using FIX YA
