Code: P0303 Misfire on cylinder #3.

Ford - Ranger :: Cylinder Misfire - Spark Plugs Keep Going Bad
I purchased a 2000 Ford Ranger last year. Within the first two months of ownership, the vehicle was having a cylinder 4 misfire. To fix it, I replaced the fuel filter, plugs, wires and cap - replacing the wires, plugs and cap fixed the issue. The issue went away for four months when cylinder 4 misfired again. I brought it to a repair shop and they again replaced the wires and plugs. The vehicle now has a cylinder 6 misfire.
There has to be something causing these plugs to continually go bad. Rather than just replacing the plugs again, I'd like to attempt to be proactive and fix the root of the issue. I've googled the issue and some of the forums seem to indicate a bad EGR valve.
Golf IV / Jetta IV :: Misfire On Cylinder 3 - Replace All Plugs?
After getting some misfire and hesitation (code reading says misfire on cylinder 3), it looks like I'll be doing my first spark plug change on my 24V VR6. I've ordered all of the plugs, and have made sure that I'v got all my tools on hand. Hopefully, the DIY's I've found on Vortex will be as useful as they look .
My car has 163K on the clock, and spark plug change has been on my short list of to-do items, as I'm not sure of the maintenance history of the car. Hopefully, the spark plugs will do the trick, but coil packs will be done soon too.
Would it be OK to change just the coilpack on cylinder 3 and leave the others alone if they are all working OK? Or just shell out the cash to change all six at once?
Pontiac - Grandprix :: 2004 - Cylinder 3 Misfire And Gas On Spark Plugs
Ok , i have a 2004 Pontiac Grand Prix GT V6 GM 3.8, my car didnt have any misfires until after i changed my Lower Intake Manifold Gaskets. After changing the gaskets and putting everything back together. The car ran fine. The next day i took it an hour and 30 min away, while driving there it started misfiring and shaking,rough idle at an hour into the trip. The check engine light went to blinking. The Next day i drove it all the way back home in the condition. Put code scanner to it, and received P0303 "Cylinder 3 Misfire":
So i automatically assumed it was the coil pack because i just installed new wires and plugs a week before changing Lower Intake manifold Gasket. Bought new coil pack. Still getting rough idle and P0303 code. So i decided to take a look at Cylinder 3 Spark plug and it was dry black, carbon fouled:
So went and bought new spark plug, installed it, started car and still rough idle and misfiring. Took the new spark plug out and it had been FOULED also ( DRY BLACK AGAIN). So i was told to switch a coil pack around. I did it and the started car, took away some of the rough idle, car actually wasn't misfring or shaking, would run smooth for about 5-8 seconds then start misfiring (Didn't that until i switch coil packs around).
Next Decided to pull out the rest of the plugs from the back and all of them were WET with GAS!! and 2 Spark plugs are just dry fouled!! (Cylinder 3, Cylinder 1). If I can figure this out i will fully have my car back to running correctly.

Yesterday I decided to tune up my 2003 5.4 for the 1st time at 82k miles. I replaced all 8 coils with MSD coils & motorcraft plugs. After doing so I went to turn over the ignition & got 1 single click, motor wouldn't even turn over. Battery is 3 months. Truck ran just fine prior to tune up other than the slight misfire I was starting to get.
When I was working on the passenger side I did disconnect the big bracket that had the multiple wire harness on the fire wall underneath the starter solenoid to gain access to the rear plug/coil. Where to start troubleshooting? I checked the fuses under the hood & dash but nothing looked blown.
On a side note I remember when I was putting everything away I tried to lock the truck with the Ford factory transmitter & it wouldn't lock?! I had to open the door & press the power lock button to lock the doors.

my dad has a 2001 Passat and he recently had his check engine light come on. We had it checked by a guy who owns a tester (snap on) and it comes up with a misfire fault on cyl #2. Wire looks good, I didn't have tools with me so I couldn't take a plug out, but do you think it could be a bad spark plug? Bad coil? Car has 89K on it.

Back on February 14th ,I had my 2013 elantra gls towed to the service dept for arching and a rough idle. It was a code for #3 cylinder and a cleaning of the coils. Everything was good until again this morning ,only this time the engine light is on with all the same symptoms. There is 14,800 mile on it, I hope they get it right this time because it is a PITA to work this around my schedule at work.
View 7 RepliesFord Excursion :: Codes For Cylinder 8 And Then 7 - 2 Bad Coils In 3 Days
So on Thursday night I replaced all of the plugs and boots on my 01 v10. I used Autolite 103's and Autolite boots. On Saturday the truck threw a code for cylinder 8. I bought a bag of 8 used coils off a buddy who has a mustang buy a few months ago so I put one on, cleared the code and the miss went away. On the way home tonight the truck started missing hard, but no CEL. I use torque, so i did a scan anyway and it pulled a code for cylinder 7. I haven't been out to troubleshoot yet. Could I have done something wrong for 2 coils to go in such a short amount of time? I followed the write up in the tech folder. Used proper torque specs, dielectric grease, and anti-seize on everything.

View 8 RepliesPassat (B7) :: Flashing CEL - Cylinder Misfire At 50K Miles
Today I started up my 2013 Passat SEL up and it started shaking and idling very strange. A few seconds later I had a flashing CEL so I decided to turn her off. I waited about 5 minutes (after cursing for about 4.5 if those minutes) and tried again. This time the car started and everything was fine, no CEL, no other issues. I drove for about 10 miles, shut off the engine and re-started about 5 more times with no issues.
I just had the car in for the 50K mile service at VW and everything checked out ok. I copied the VAGCON report below and I also sent it to my service manager to get his opinion. What I should do?
