Question about Volkswagen Polo

1 Answer

Cylinder coil 1 burnt out. Replaced with new coil pack cylinder 1. Also detected was a load fault from alternator on the DF wires. All four spark plugs were replaced and the wires were then ok. Also the fuse for the injector duration was replaced. After all this was done a few days later I drove the car (185 miles) 2 cylinder burnt out. Would be obliged if you could give me the reason for this reoccurrance over a short period of time. Kind Regards Dale Doherty

If you mean the number 2 coil then it is of that age. Replace them all to avoid premature failure.

well..fuel injection systems are more than the electronic part. I suspect you are dealing with compression or injector fouling issues..

yes they are but you need to check and replace the plug wire itself. that usually causes a misfire code

SOURCE: #5 cylinder misfire

I have a corolla and had #4 cylinder misfire also diagnosed at autozone. After changing the spark plugs, problem persisted, along with the same error code, so they recommended changing the spark plug wires, and that is what fixed it. I would have changed the rotor cap too, but was low on dough. Glad that was not the problem.

ignition mod. grounds,pcm or timing belt could all be it but, I would have to look at timing first.

This Sounds Like a COIL PACK Problem

2004 chrysler van 3.8 motor replaced coil pack still doesnt fire number 4 cylinder


If the coil pack has a four wire connector, one wire is primary voltage, the other three wires are ground, one ground for each coil, one coil fires two spark plugs. If problem with coil or ground, you would lose spark for two spark plugs. Did you visually check for spark, everywhere? What about the spark plug wire or the spark plug, itself?

COIL PACK WIRING DIAGRAM


The coil pack wiring is relatively straightforward though the exact wiring, colours and suchlike will vary a little from car to car.

A 4 cylinder engine will have a coilpack containing four individual ignition coils - one for each cylinder, but they are likely to be wired as if there is only two. This is to simplify the wiring and to cut a little unnecessary complication from the ECU.
Effectively those four coils are two pairs of coils - the primary windings of coils one and four are wired in series and similarly the primary windings of coils two and three.

When cylinder number one fires a spark is also generated by coil number four but causes no effect as that cylinder is at the top of the exhause stroke. This is called the wasted spark principle.

The same effect can be obtained by using a single coil per two cylinders of a type which has a single secondary winding which is completely isolated or not grounded in any way. One end feeds one spark plug and the other end is also terminated in a spark plug wire and terminal.

This simplification means the coil pack (4 cylinder example) is fed by only three or four wires (usually four).

I hope this helps.

Cylinder # 3 has a misfire...#1) Defective coil on plug or the spark plug itself...#2) Contaminated fuel injector...See drawings below...The coil pack is the smaller of the two and sits to the rear of engine it is the most probable cause...Although the spark plug or the ignition wire (connection between plug and coil pack) could be at fault...so, before you invest in a new coil pack...Remove from both ends the wire from #3 and switch it with #2...if the fault code changes to p0302 that wire is bad...next Install a new set of plugs....Fault still present? replace the coil pack.....Unless recently changed new plugs and wires are a plus even if fault remains...saailer

2003 Hyundai Sonata with 4 cyl. PO301 error code. Have replaced spark plugs, wires, coil packs, and mass air flow sensor. Replaced air filter due to heavy gas smell. Car was starting after tapping gas 3...


P0301 - Cylinder 1 Misfire Detected.

Possible Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak at cylinder

Possible Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1

Being you have a heavy gas smell I would look into the injectors. If injector #1 is over producing it can cause a misfire. Test your compression and fuel pressure.

I have a p0303 trouble code on my 1999 Passat. Missfire on #3 cylinder. Coil is ok, I'm lost.


coil packs very prone to failing... check compression for good readings (at least 100 - 120psi) if okay try new spark plug as these can fail under load and its the cheapest part to replace to eliminate. if misfire still present swap cylinder 3 coil with cylinder 1 coil and see if fault code moves to cylinder 1. hope this advice helps

I have a ford explorer 99 but it's giving a error code PO306 what do u think it is


It sounds like a misfire. Check spark plugs 5 and 6. It could be bad fuel, bad plug wire, or weak coil. Check the fuel injectors as well. Other possible causes could be an egr valve stuck open, vacuum leaks, low fuel pressure.

Coil pack


On all four cylinder sit on top of engine toward back, follow spark plug wire from top of valve cove to coil pack. On six cylinder engine the ignition coil sit inside the distributor under the cap where the spark plug wires go.

A4 Quattro,misfire detected cyl4.


Coil packs are relatively common failures on the B5 A4, although it's usually on the four-cylinder turbo. Swap the coil pack with another one on the bracket, clear the code, and then run the car and scan for codes. If the code doesn't change, then the problem is plug or wire. If it follows to a new cylinder driven by the same coil that is currently failing at cylinder four, then it's the coil pack.
