Ford - Taurus :: CEL Came On With P305 Code / Cylinder 5 Misfire Detected
Apr 2, 2011
Wife's car - 2005 Taurus, 6 cyl, 3L, OHV, 83K miles. CEL came on and code came back as "P305 - cylinder 5 misfire detected". The car had been running rough. I changed the plugs, wires and coil. After changing these (and clearing the code) the car seemed to run better for about a week. Today it suddenly started running rough again and the CEL came on with the same code. I'm guessing now this is probably fuel related as opposed to spark related??? As a side comment, the tachometer has been fluctuating as of late as well (again, intermittently).

New to diesel trucks and wondered if this recurring code is a serious problem. I clear DTC and truck will run fine. Might stay off for 2 days or 2 months and same code comes back. Truck seems to run just fine even with service light on.

01 Taurus, 3.0 pushrod motor. Single 6 pack style coil. I replaced worn plugs 2 months ago for misfire. Car seemed to run fine. Now, I have misfire again. Code is for single cyl, 0303. Would u expect plug to foul, or bad wire, or possibly bad coil? I don't know how these ford coil packs fail. Can u lose 1 or more spark outputs with them?

I have a 2009 Corolla S 1.8 with a manual transmission and 30,000 miles. About a month ago the check engine light came on throwing a PO302 code (cylinder 2 misfire detected). I reset the check engine light and drove it about a week before the check engine light reappeared again with the PO302 code. I swapped the spark plugs on cylinders 2 and 3 and reset the check engine light, the PO302 soon reappeared. I swapped the coils on cylinders 2 and 4, and reset the check engine light, the PO302 soon reappeared. I swapped the fuel injectors on cylinders 2 and 3, and reset the check engine light, the PO302 soon reappeared.

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 guess misfires are a rite of passage for these vehicles. I purchased it only a week ago. Welcome to Hyundai...
The car has 53k kms. It's throwing P0300 and P030X on all cylinders. There was one instance of P0128. The engine runs smoothly and doesn't seem to down on power, although I have nothing to compare it to. The only performance issue is that it acts as if there is a rev limiter at 6k rpm. It sputters and stops pulling above 6k. Strangely, it doesn't throw the codes under load. The light flashes while it's running steady-state.
I pulled the plugs and they appeared to be in excellent condition with no erosion of the electrodes. The ash is slightly more white than I would expect, making me wonder about it being excessively lean. I called the dealer. They told me that coils are problematic. Replacing the coils made no difference.
That lead me here. I found the thread "Check engine light flashes then stays solid," which referenced the ECM update.
Interestingly, of the codes mentioned on the TSB, the car is having all but the last two.
- P0300: Random/Multiple Cylinder Misfire Detected.
- P0301: Cylinder 1 - Misfire Detected.
- P0302: Cylinder 2 - Misfire Detected.
- P0303: Cylinder 3 - Misfire Detected.
- P0304: Cylinder 4 - Misfire Detected.
- P0128: Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature).
- P0328: Knock Sensor 1 Circuit High Input.
- P0461: Fuel Level Sensor A Circuit Range/Performance.

Question about a 4th cylinder misfire question? The engine light has been on off and on for about one year. I have not had any problems with performance until about one week ago. sometimes it shakes and the engine light flashes when it is idling. Today my husband drove it, and it would not accelerate when he put his foot on the gas, but it would pick up speed when he left his foot off the gas! Weird. This is an old car (2001 Ford Taurus station wagon) with 137,000 miles on it. We need this car.

So I start to drive home as I was driving home my check engine start to blink and then it stay on. When I got home and park the car I shut off ,then start it up again then the check engine light was off but the hesitation was still there. Then I got my computer and got the vagcom and got this code :
16684-random/multiple cylinder misfire detected

2008 Buick Lacrosse CXL .. My son said the Oil pressure low light came on when he tried to start the car. It didn't want to start.
When I got there two hours later, it started but had a check engine light. But no low oil pressure light. Sounded like it was missing.
Code from computer came back P0300 "Random/Multiple Cylinder Misfire Detected". I cleared the code. Revved the engine to about 2000 RPM's and the CEL came back on.
Same code. When idling it feels like it's missing. The plugs look good, I am going to replace the ICM.

I bought my first VW about 3 months ago (so excited!) It's a 2003 Passat, 5 spd, 1.8t. I've had one thing happen so far (until yesterday). On 4 separate occasions when I'd go to start it, it would crank for a few seconds before it would start. Then once it was running the EPC light would turn on. It seemed to be running normally but I turned it off and restarted it and it started normally and the light extinguished (the first three times). The last time (about a week and a half ago) it kept doing it each time I started it, and upon starting probably the 4th time in a row the MIL came on. I drove it about a mile, turned it off for a few minutes, then turned it back on and it started normally with no malfunction lights on. It's been normal since then. Until yesterday...
Yesterday as I'm accelerating from a stop light (I think I was in 3rd) all of the sudden the engine started running really rough and the MIL came on. I turned around and drove about 2 miles back to where I started at about 20mph. The MIL would be steady while coasting and flash while pressing the accelerator. I got a hold of a diagnostic computer and it came up with 3 codes...
1) P0322 Ignition/Dist Engine Speed Input Circuit No Signal
2) P0302 Cylinder 2 Misfire Detected
3) P0302 Cylinder 2 Misfire Detected PENDING

I recently bought my 2010 gti used with 62k miles on it about 3weeks ago. The car had an carbonio intake stage 1 and a stage 1 tune from Apr when I had bought it. On the test drive and for the first two weeks I had it I did not have any problems. A few days ago on a cold start my car threw an MIL and it was flashing. When I got to school I plugged it into the obd2 scanner. Code read P0303: misfire cylinder 3 detected.
My teacher and I went over possibilities of the misfire. Coil pack, plugs , injector, valve float( even tho this should not occur at 1300rpm cold start) we also thought that maybe because the car is direct injection the valve was not closing all the way due to carbon build up on the top of my valves which in this case I'm glad I don't have an interference head. I moved around the coil packs. What is the cause of this? I'm only misfiring at start and when the engine isn't warms up to operating temp.

I had a consistent misfire on this car and finally got a P0301 trouble code. I installed new Autolite AP 104 plugs and wires. Now, when I start the engine. it runs perfectly. But when I put it in gear, it misfires. After a minute or so, the misfire clears and the engine runs perfectly. I have not received another trouble code. One thing I did notice is that the plugs I took out (Motorcraft AWSF 32P) had a much larger gap than the .044 the associate at AutoZone set the new plugs to.
