Santa Fe (CM - 2007-12) :: 2008 - Random Cylinder Misfire / Vehicle Shuttered And Driving Power Lost
Mar 27, 2012
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?

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...

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?

Our santa fe 2008 diesel randomly stalls. Most of the time the stall happens after at least 15mins of driving but I am not sure if its just a coincidence. It only happens when the car is stopped. When it happens, i put the car in park, turn off AC, then turn the car back on. It starts right up but is a bit rumbling like it will stall again. When i press the accelerator there is no response.
If I turn on the AC or turn the wheels, it dies. If i put it in drive or reverse it also dies. That happens around 3-5 times, then after that, everything is good again. Accelerator responds normally, car doesn't stall. Its driving me crazy! Whats worse is sometimes it doesn't occur for 1month! Then all of a sudden it stalls again. Bought the car 2nd hand and since january it died around 8-10 times.
I brought it to a reputable mechanic and they checked the fuel system. Replaced the fuel filter, fuel sensor. They even tried a different pump and sanction valve and it still didn't fix it. They kinda concluded that its not in the fuel system already, but they are at a loss. Its very hard to trigger since we don't know what really causes the stalling. All we know is that it only occurred when the car is stopped.

We've got a 2006 F150 with a 5.4 in it. One of the new kids was told to change the spark plugs, then when I went to start the truck the next day it was missing bad. Plugged in the Ford IDS, number 7 cylinder is dead. Only codes are for that cylinder misfire, and random miss on startup. So, I double checked the kids work and it was all fine. Tried putting a new plug in, didn't work. Moved the coil to a different cylinder to see if the miss would jump, stayed on number 7.
Used a noid light to verify COP harness was working, and it was. Put a new coil on it anyway since I had one, still missing. Used noid light to verify signal going to injector for the cylinder. Signal was good, replaced the injector for the cylinder. Still misfiring. Ran a compression test and the cylinder has good compression. The threads for the plug are fine, not cross threaded or torn out. The only thing I can think is that the PCM has gone bad in a way that its firing the injector/COP, but doing so at the wrong time some how.
Every other cylinder is running fine, O2 sensors fine. PCM isn't trimming anything back to account for anything, and if it was it would do it to multiple cylinders to keep the engine balanced. Cant think of any more tests, and I don't believe there is anyway that the airflow could be restricted to only 1 cylinder, but I could be wrong. Wanna try and solve this to keep from sending it to the dealer.

Truck Specs:
2008 f250 super duty 5.4l
78xxx miles
4x4
Automatic
Issue:
P0300 (random misfire detected)
P0307 (cylinder 7 misfire)
Let's start from the beginning...
I was getting the notorious 5.4l ticking sound. After doing research on this issue. I found that it could be a few different issues including:
Cam Phasers
VCT solenoid(s)
Loud injectors
Valves
Exhaust leak
Loose spark plug
The list could possibly go on, but these being top concerns or issues to look into.
I took it to my mechanic and wanted him to research the ticking problem. This was my primary concern due to it was getting worse over time. I didn't want to do more damage than what was possibly already done. I told him to go ahead and change the spark plugs while you're checking into what's going on. (I know those plugs can break and I didn't want to do that.)
At any rate... the plugs got changed to motocraft brand (I know the trucks can be finicky with the parts you put back into them so I went with the motocrafts to avoid any complications.) After the plugs were changed, he told me that the ticking was caused from a blown exhaust manifold gasket (yay me... not internal parts or anything too serious. Sweet!)
I had to reschedule to get the gasket done, but knowing what it was now I wasn't too concerned about driving it. So I did. The new plugs are also in the truck at this time. I drove it the next day and right away.. I noticed a misfire. Thought maybe the plug was bad. I told my mechanic about it and he said... Sounds like a COP to me.
So I get a new COP. Okay.. easy fix. Installed it and still got a misfire. Told my mechanic and he said get another COP. So I'm thinking.. "Okay.. get a new part to fix a new part.. sounds logical.. lol" so I do what he thinks might be best. I replace the COP with another new one and it's still misfiring. The new cops are also motocraft brand as well.
Okay... next step.. he claims it may be a VCT solenoid issue. At this point I don't care.. I just want my truck fixed. So he replaces the driver side solenoid. Still misfiring..
So after doing some research on the scanner... we locate some issues that are the exact symptoms I'm having. Misfire.. at low rpm.. during cruise control.. and a sudden at idle.
This information states for this drivability issue.. to spray injector cleaner/carb cleaner into the engine and possibly clean it out. Makes sense. He did this as well as changed the fuel filter. Also did a pressure test on the injectors to make sure they were good. They were. After spraying and cleaning it out, it was taken for a test drive and it seemed okay... but not perfect. The next day.. the misfire came back.
He said that if the misfire returns, that I need to contact the dealership and see if there is a pcm update. The dealership said there probably is but can't tell me until the computer is hooked up to it. (Of course there is a charge when it's hooked up) again.. whatever.. I just want it fixed. The truck is scheduled to go in next Wednesday for that. If that doesn't fix it, my mechanic said cam phasers possibly bUT still not sure for sure..

I had plugs and wires changed to try clear code. Car seemed to do some better but while trying to go up a steep hill car started stuttering and jerking. Power went out of car and check engine light started blinking fast. After let the car sit for bout 45mins car started running fine again and light stopped flashing but remained on. Code read cylinder2 misfire again.

My 07 3.3 SF is throwing P0154 and P0300 codes. Autozone said the P0154 is Bank 2 pre-cat O2 sensor. But exactly which one? The P0300 is random misfire. Could they be related?

Driving down the road, vehicle lost all electrical power and died. There doesn't appear to be any juice at all to start it. The battery is fine (along with the terminals), the starter is okay too (although I don't see why that would affect total electrical flow). There were not any alarms on the vehicle. Is it the fuse box (negative terminal) or possibly the alternator? The alternator had been charging, and the battery showed that it had juice left in it. What would cause the vehicle to just die like that, in the middle of driving it? It's an LS type blazer with a 4.3 L engine.

I have a 2007 F-150 5.4L V3 Lariat with 90,000 miles on it. For about 5-6 months now I have noticed a strong sputtering when I am driving at low RPM's around the 44-50 mph range. When I lightly give it gas the sputtering begins and doesn't cease until I accelerate out of the current gear into a higher RPM/speed. This has become more pronounced over the last few weeks so my mechanic replaced the fuel flter and checked to make sure the pump was working as well. We also added some 5w-30 oil to make it full, even though 5-20 is preferred.
Truck ran smooth initially but then it got worse with the sputtering. A couple of days later I filled up my gas tank and as I pulled out of the station my truck shuttered alot and died. the CEL came on, LOP came on, and even the low tire pressure light came on. The truck will not start now, but it cranks smooth and strong until the battery loses power. I had the truck towed and then we reset the gas shut of toggle, sprayed starting fluid in the air intake, and checked all fuses, as well as the fuel pump engagement. Still no ignition. Next we replaced all spark plugs(4.5 hours later). Still no ignition. Only CEL light and low tire pressure light. I bought it used less than 18 months ago?

I know there is a tun of info on the spark plug problem on the f-150. Here is the problem I have and I don't know where else to look.
Cylinder #3 misfires
1. swapped coil with #2 cylinder and still throws #3 misfire code.
2. Changed the plug on #3 and still the same code #3 misfire.
Where to look next?

When driving I seem to be constantly applying pressure to the left side of my steering wheel to keep the vehicle from moving to the right. I've had the car aligned made sure my tire pressures were correct and had my mechanic check the undercarriage to make sure ball joints tie rod ends etc. are all in good working order. Despite all this the vehicle seems to want to wander right and I'm constantly putting pressure on the left side of the steering wheel.

Had the following problems with my 2009 Santa Fe: Audio system would randomly reset when playing MP3 from USB drive, Headlights would dim/flicker when bakes depressed, LED lights on dash would flicker, random stalling while driving. Finally just died and would not start. The Hazard lights would not work only a bit of buzzing from the relay. Checked Battery, connectors, etc. All looked good. Measured voltage at fusebox (inside) and found it dropped from 12v to 4v when I put the hazard switch on. Showed there was a connection problem of some kind.
Finally used a jumper cable from the battery negative terminal to an ground point inside the cabin. Bingo that fixed all the problems, car started, lights were good, hazards worked. As a permanent fix I ran a wire from where the negative terminal of the battery connects to the frame, then drilled a hole in the firewall and ran the wire into the cabin. Connected the wire to a ground point in the cabin. Used a heavy gauge stranded wire. you can try this out with lamp cord as a temporary fix, but I'd use something heavier for a permanent fix. All problems have gone. No flickering, no stalling... This may be a problem on other models from what I've read in some forums (unexplained stalling - check the grounding in the cabin..).

1999 Passat 2.8L. New coil pack assembly, wires, plugs, valve cover gasket(oil in plug holes). Misfire at idle and low rpm. Driving at higher rpm's misfire seems to go away. Codes are random misfire and cyl 1 misfire. Need to know if I would get an injector code if a fault or If that motor has problem with faulty cams or springs or any other common problems. I am going to do a compression check this weekend I'll update that info.....

Replaced my water pump March 2nd using the "From Below" method. Started the car after and the check engine light was on and water pump was no longer leaking. I drove the GTI to Advance (15 Mins away) it drove fine and I pulled two codes.
P0300 - Random Multiple/Cylinder Misfire
P0301 - Cylinder 1 Misfire
The car pulled and drove normally. The next day the car is misfiring badly. Hesitation and bucks when accelerating until roughly 3k then smooths out.
I will swap my coilpacks and check if the misfire moves as soon as I can get my hands on an OBD2 Scan Tool.
From what I understand about the VR6 :
-The water pump runs off the serpentine belt
-Camshaft timing is controlled by the timing chain.
-Timing chain is not affected by the serpentine belt/pulleys.
Questions :
-Can turning the Crankshaft Pulley affect timing?
-Can that be the cause of the misfire?

About a month ago my wife's 2000 Jetta with the VR6 engine in it started acting up and throwing codes. The codes it threw were for random misfire, misfire in cylinder 2, and misfire in cylinder 5. Starting out, we changed spark plugs, fuel filter, and made sure the injectors were clean.
The problem didn't go away so we water tested the coil and wires, but they passed that test. The wires were quite old and out of spec, while the coil was in-spec across all terminals, according to the vehicle service manual, so we installed some new OEM leads this weekend. While installing the leads we noticed a disconnected vacuum line and reconnected that as well.
The vehicle was driving great for two and a half days, then today while I was sitting at a stop light, it started missing really badly and felt like it was going to kill. It did this for about 5 seconds, then recovered and ran smooth for about 5 seconds, before getting really rough until I started driving when the light changed. It didn't do it when I drove it a few hours later at all. This episode didn't throw any codes either.
What could be causing this issue? Would the MAF cause the intermittent missing, or is it possible that the computer is going bad?
