Ford F-150 (2004-2008) :: Power Loss / Check Engine Light / Misfire On Cylinder 5 And 6
I have a 2008 FX2 5.4L F150. Recently it began to lose power on a friend driving it out of town. He got a check engine light then it just progressively became unable to produce power. It ran but he got down to 10 mph before he could get to a firestone. I got it to a local Ford dealer and they say i need a new engine. They gave me codes for cam sensor and timing and #5 and #6 misfire. (344, 345)
No oil in radiator, no water in oil. The crazy thing is it runs like the day i bought it in Park. But once in gear it begins to cough and then eventually shudders and dies. I haven't changed plugs ever. I know... At about 75 miles it began to idle rough at times and in reverse. But once I revved up it went away.
I replaced both cam sensors but no luck. Today i put it on a tow truck to get a second opinion from a local engine shop. I actually backed it down my driveway, and pulled up to the tow truck with no issues. weird...
Accent MC (2006-11) :: 2008 SE - Check Engine Light Indicating A Misfire Cylinder 3 And 4
I'm having problems with my accent, is been running not so good , and had a check engine light, indicating a misfire cylinder 3 and 4, i was told to put a can of Seafoam on the gas tank, but that didn't work. I replace the spark plugs (not the wire) and air filter and still running bad. Is not happening all the time (check engine light) but you can tell is running ruff at all time. I don't know if I need to change the spark plugs wires. I don't think is the spark plugs wire, they don't look bad or damage.
View 6 RepliesPrius (2004-09) :: Check Engine Light With PO301 Cylinder Misfire Code
I bought my 2008 Prius 9-14 with 29,000 miles on it. (rebuilt title-big mistake I now know). I found out after I bought it that it had sat for 5 years before it was rebuilt) I figured it was a miracle the hybrid battery even worked.
I had no problems until 2-4-15 when check engine light was flashing and the car was shaking. The local mechanic said was the “clutch” (torque converter), took the engine and transmission out of the car to fix it ($2200). But he realized the mass air flow sensor (MAP) was not working even after he put a new one in so had me take the car to the Toyota dealer. The dealer found a cut in the engine harness and advised me to replace the harness which he said would cost $2800. The local mechanic saw the cut via my cell phone photo and offered to fix it for free which he did.
The next day check engine light comes on after driven 25 miles with code PO 301. (means misfires in cylinder one). The local mechanic switches cylinder 1 with 4, same code the next day, local mechanic switches the coils to the cylinders, still the next day the same code. He switched the fuel injectors. Same problem of cylinder 1 misfire. He cleaned the oil out of the intake manifold, did fuel injection cleaning, and cleaned gunk out of the fuel line. Car would drive good about 20 miles then same check engine light, same code, sometimes code PO300 (random multiple misfires).
Audi - A6 :: 2004 - Check Engine Light Intermittently Flashing / Misfire On Cylinder 2 And 5
I have a 2004 Audi A6 wagon that has an intermittently flashing check engine light. I took it to the dealership to have the codes read and they told me that they got codes for Cylinder 2 and Cylinder 5 misfires. Additionally they got a code saying the Engine Coolant Temperature Sender was electronically faulty. What is this part and what does it do? Is it essential to fix it immediately?
The dealership recommended changing the spark plugs and the air filters for the cylinder misfire issue. We are also talking about replacing the timing belt since the car has 105k miles on it. I know there are several other parts that are replaced during the timing belt replacement (like the water pump, thermostat, oil seals, etc). Is it essential to replace these items if there is no immediate need to do so?
Ford Excursion :: Check Engine Light And Cylinder 5 Misfire
So when I bought the car, it had a check engine light. I had it checked it said cylinder 5 misfire. I assumed it was the glow plug so I bought it and replaced the glow plugs myself. Check engine light went away for about a day then came back on. Got it checked again and still said cylinder 5 misfire. This is my first diesel and I'm clueless as to what's wrong.

Ford F-150 (2004-2008) :: 2006 - Shuddering And Check Engine Light Came On - Multiple Misfire Detected
I have a 2006 F150 4x4 5.4. For a long time it idled poorly and would take 2 trys to start. Today it started shuddering and the engine light came on. The engine light went off but it still runs rough and smells of gas from the exhaust. It is not very drivable and I can't afford to take it in. I have lots of mechanical experience but not with this electronic junk and need diagnosing the problem. I have a code tester and this is what it said.

Ford F-150 (2004-2008) :: 2005 - Cylinder 5 Misfire - Spark Plug Replacement?
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?
Ford Ranger / B-Series :: 2000 - Check Engine Light / Misfire On Cylinder 5
OK, got a check engine light today when I fired up the Ranger. Like I posted previously it is running kind of rough so guess I know why now.
Took it down and got the codes read it have a miss fire on cylinder 5. Picked up some plugs and wires, got to get those E3's out of there, but kind of think that's really not going to fix the problem. So that probably leaves the coil pack or injectors.
So what's the consensus on the best coils to use? Also, being an 18 wheeler for more years than I care to remember, I've learned swapping just 1 injector is never the way to go. So whats the best type of injectors to get and where the best place to get them should it come to that?
Oh, it's a 2000 3.0L Flex fuel 5 speed.
Ford - F150 :: Check Engine Light Started Flashing / Cylinder 4 Misfire Code
1997 Ford F150 - 133K Miles - 6cyl - 4.2L. This is a truck that gets less than 2K/year put on it. Has had "issues" with worn bearings and holding oil pressure for a few years now. Yesterday, the check engine light started flashing (as opposed to solidly lit) and the code came back as a cylinder #4 misfire (only the one code). The truck was clearly not firing on all cylinders and at idle, ran terribly (couldn't be driven). I just did a compression test on all the cylinders and all measured around 140-145psi except the #4 which read almost 170psi. I rechecked this a few times as well as a couple of the others and am now sure of the results. What could cause this one cylinder to have a higher compression ? Is whatever is causing this increase in the compression, also be the cause of them misfire ?? I'm stumped here and quite frankly, expected the compression on the #4 cylinder to be really low as opposed to the others.

Also just to double check, the cylinder number is 1, 3, 5, 7 for the passenger side front to back right? And 2, 4, 6, 8 for drivers side? And front to back means when looking at the front of the car? 2001 7.3 Excursion Limited with 232k miles...
Ford F-150 (2004-2008) :: 2005 - Shudder At 65 Or 75 Mph - Check Engine Light Came On
I have a 2005 f-150 with the 5.4 engine. Bought it new and now it has 107,000 miles on it. Recently,it would have a shudder at 65 or 75 mph then the passing gear would kick on and it worked perfectly. The warning check engine light came on,then,when it acted up it would flash intermittently. Took it in to the dealership and put it on the diagnosis machine. Said cylinders 2,3, and seven were not steady etc?? So,after he took it out and drove it he said those particular cylinder walls were scored. I put in a K-N air filter at about 50,000 miles,and he said that they do not seal properly and dust got by the filter into the intake and got into the engine and did this damage. One think he found was a bad coil on one cylinder and replaced it. And just as he said,when I got on the road home I romped on it and it cut out and the intermittent signal showed again! He said that that would happen and it did.
View 2 RepliesPassat (B5) :: V6 Check Engine Light - Misfire In Cylinder 4
I'll try to break this down as best I can. I went to my mechanic this am with a check engine light. My suspicion is 02 sensors. This was confirmed as a problem area, but separate they said I had a spuratic misfire in cylinder 4. With that info, i pulled the plug to inspect (I had just installed new ngks in it and they have 18,000K on em.
I put beldon wires on about 8k ago.) plug looked to be normal, but there was definitely a puddle of oil from the valve cover leaking. Oil went into the cylinder head but I didn't really think that was an issue. Nothing abnormal jumped out at me so I reinstalled plug and checked all wire connections at both ends and called it a day.
Then I drove it. Check engine light flashing. Major performance stutters, etc. I drove it for about 20 miles and hoped it was just the oil raising hell in there and it would burn off eventually. It hasn't gone away yet. Maybe coil pack. Can the single portions of that pack be replaced, all i see them sell is the full three as a unit.
Chevrolet - S-10 :: Check Engine Light Come On / 4th Cylinder Misfire
2000 Chevy S10 pickup
Had the check engine light come on, and when I checked on the code it gave a 4th cylinder misfire. Autozone instructed me to simply replace my spark plug with a new oem plug.
I replaced the spark plug as instructed. After about an hour of driving, the check engine light goes off and I think, great! Problem solved. However, another hour of driving and the check engine light is back on again, without going away.
I headed back to autozone to get a readout, just to find that it's the same code. So I put another spark plug in. Same result - check engine light goes off after an hour, only to come back on again permanently after another hour.
Now, normally I would think, this must be the spark plug line that needs replacement,however I am sure there must be some clue in the fact that the check engine light turned off for an hour.
By the way, not sure if relevant, but I also found a lot of build up around the spark plug before I initially changed it.In fact, there was so much that I had to scrape around the plug with an awl, and blow out the crud with a compressor,just to get my socket into place without there being crud in the way.
Any clue what that check engine off/on clue might be?
Passat (B6) :: Check Engine Light - Cylinder 4 Misfire
Got the flashing check engine light and loss of power for few seconds and then the light stayed still, from time to time it blinks for few secs, usually when I push the gas pedal little bit more but it stays still, flashed only twice in 2 days for seconds. I connected computer (not VAG) and it says "Cylinder 4 misfire". I have app scheduled with my mechanic this Thursday, but still need to commute to work. Is it safe to drive?
View 7 RepliesFord - Ranger :: 1997 - Check Engine Light On With P302 Computer Code / Misfire On Cylinder 2
1997 Ford Ranger with 190K miles has check engine light on with P302 computer code, meaning misfire on cylinder 2. Engine runs rough at idle only once it warms up, which only takes a minute. It is usually fine while driving, but it's a lot easier to feel a misfire at lower RPMs than at higher ones. Added fuel injector cleaner to gas for a couple tanks, no change. My mechanic has checked spark plugs, fuel injector, o2 sensor, and everything is ok. Dry compression test shows good compression. He thinks it may be a valve sticking, which means a valve job: expensive. Is there anything else that can be done? Why is there no misfire when it is first started?

I have a 2003 ranger and have had ongoing problems with misfire cylinder six and have had three different mechanics diagnose the problem as a bad ground. I have replaced all plugs, wires, coil pack, injectors and am constantly pulling the plug on cylinder six, cleaning and often replacing, I also disconnect the battery so it resets the check engine light and it runs fine for about 100 miles and starts running rough again and on goes the check engine light.

I plugged in a OBD2 reader and its show misfire on Cylinder 1.
I haven't driven the car for 4 days, and when i started the engine this morning, the engine show knocking when the regular engine kicks in (rough). i will be bringing the car in tomorrow (dealer). my car is a 2011 with 16k miles, strange for this to happen so early in age.
Elantra XD (2001-06) :: Check Engine Light (cylinder 3 Misfire)
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.
