I am trying to fix my friend's 03 Santa Fe 2.7L with 325K miles on it. Pulled the codes and he has misfire in #3, 6 and a random one. It doesn't do it all the time, and when it does do it he can sometimes shut it off and restart it and it will be fine.
What is the likely culprit causing the misfires and how to test it? He can't just throw parts at it.
Passat (B5) :: 2001 - CEL Came On / Misfire On Cylinder 2?
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.

I have a 2001 ford windstar the codes are bank 1 lean (wires have been cut) could this cause the miss fire on the #1 and 3 cylinders? The previous owner put copper plugs in it instead of platinum. How hard is it to change the plugs?
View 6 RepliesGolf IV / Jetta IV :: 2001 - Misfire On Cylinder 4
New to the VW world but I am not out of my element for I am a Porsche guy. So I feel right at home. Last night I picked up a 2001 wolfy Jetta with a 1.8t on the cheap with a misfire on cylinder 4.
I have verified I have no spark on 4. I have confirmed the issue is not the spark plug, coil pack by swap and see method. My coil pack and plug work fine on another cylinder. I reset my cels and here are the new ones that pop up:
a 121 - gas pedal position sensor- doubt this would give me a no spark
a 304- Misfire on 4, (duh, like I needed to hear that)
a 030- bank one 02 -Doubt this would also give me a no spark condition)
In my testing:
I have good system voltage on the coil pack
I have good ground ohms
My signal wire is not shorted high or low
When I take V and ohm readings on the coil pack connection, either with the ign on or off they are all in line with the other sensors. So I don't think I have a wire issue.
The PO had the ECU replaced at a local dealer. I looked at the old ECU and it appears it had got wet at one point.
Im wondering if the same thing hasn't happened to the new one. however after they replaced the ECU they gave him the car back still broken. So it never ran even with the new ECU.
1 Where is the ECU?
2 What tells the ECU to fire the coil packs at the right time?

2002 Hyundai Santa Fe 2wd 2.7L 175,000 miles
Having misfire in #1 &4, new plugs, new wires, new coils, new cam and crank sensors, cleaned and tested fuel injectors, checked injector signal, checked timing belt.
Swapped around plugs, wires and injectors(keeping same firing order) and the # 1 & 4 will not fire. There is spark to the wires and plugs and gas thru injectors but no detonation.
With plenum and exhaust manifold removed (front only) visually checked valves. Installed new oxygen sensors while exhaust was out. Tested ecu fuses in black relay box in engine compartment.
Engine stars first time ,every time but only runs on 4 cylinders. Check engine light code reads no 4 cylinder misfire.

I have a 2001 Dodge Ram 1500 that I bought used a couple of years ago. About every 20k miles (120k miles on it now) I get a check engine light and upon diagnosis it's the 4th cylinder spark plug fouled out, every time. I change the spark plug, but the old ones are always identical in damage. The porcelain has cracked on the spark plug.

View 9 RepliesSanta FE SM (2001-06) :: Code P0306 Came Up - Cylinder 6 Misfire
I have a 2004 Santa Fe with the 3.5. Today I started it and the check engine light came on. It was not on before this. (We had a lot of wind and rain from the storm but nothing major.) And seems to be running fine. I went to the auto parts store and they ran a diagnostic and the Code P0306 came up #6 cylinder misfire. They said probably Spark plug, wire or coil for #6, then went to look up code in computer and did not have my truck so they went with Kia or Domestic, which gave different possibilities for a code P0306.
They had me buy some fuel injector cleaner as injector was on the list. The light is still on so I guess the cleaner was not the magic bullet. I spoke to a lady at another auto parts store who is a wiz when it comes to cars and has been around them and fixing them a really long time. She says the Code P0306 is Spark Plug, wire, coil #6. She has a 4cyl Hyundai car not truck and she had the code for her #4 misfire in the past and she started her repair cheapest first, Plugs, wires her code was still there she then changed the coil and that did the trick for her.
I on the other hand can't do this stuff myself. Can't afford the dealer anymore or to have a shop do a tune up AND coil if I don't need all new plugs and wires just a coil as they will charge a lot to do a lot all. And it may not need it or even be any of those things. I also suspect the dealer and shops will want to still hook up their computers to do an costly diagnostic because the light is on, even though I know the parts store already came up with a code P0306 twice. Spoke to the dealer on the phone and he already basically said they would want to do that first for $100 plus the cost of repair.
I brought the truck new. It now has 91,500 miles on it and the dealer has already done two tuneups on it in that time, Plugs and wires. I hear it probably shouldn't have even needed these tuneups in this amount of millage? So the last one was probably about 2 years ago and a few thousand miles maybe a guess 10,000-20,000 miles ago. Do you think a plug and wire would be bad already in that few miles?
Santa FE SM (2001-06) :: CEL Came Up With A Code P0303 - Cylinder 3 Misfire
I got a check engine light. I went to Auto zone to get it read & they came up with a P0303 - Cylinder 3 misfire. Since I bought the vehicle a couple of months ago, I don't know when the plugs were last changed, so I decided to change them. However . . .
Is there a secret to getting the plug boots & wires out of the hole and off the plug without wrecking the wires?
Elantra XD (2001-06) :: 2002 - CEL Flashing On And Off / Cylinder 3 Misfire
I have a 2002 Elantra with 123k on it. It has been having issues with poor acceleration, rough idle, surging, and the car just overall shakes sometimes when driving. The check engine light started flashing on and off periodically today, so I coded and it and it gave me P0303, which is a cylinder 3 misfire. I checked the spark plugs, and the cylinder 3 spark plug was pretty bad, so I went ahead and replaced all 4. The wires were in mint condition, so no issues there. I also put fuel injector cleaner in just for good measure. When I went to test the car, startup and acceleration/reverse were better, but the other symptoms still persist. What I should check next???

2001 Ford Ranger 4.0L V6... Okay so I bought my truck last September with 100K on it. Ran perfectly fine. No problems for for the first two months and then it started to misfire when at idle. Check Engine Light came on. Scanned and got a random multiple misfire code. I then changed the plugs and wires. Had to repair the threads for cylinder two. Did all that and it kind of but not really solved the problem. A few weeks later got another check engine light. Cylinder 3 misfire. Changed ignition coil. No better. Shortly thereafter I checked again whilst at work and read misfire on 3 and now 2. Currently replacing the intake manifold o-rings and cleaning out intake.
