OBD II Code 1330 : Misfire In Cyl 6 (986)

Recommended Posts

Hello all,

I have a 2002 Porsche Boxster - Automatic tiptronic transmission, 2.7L, 6 Cyl.

Last week when i took it for a drive, all of a sudden the "Check Engine" light started flashing and after a while i experienced poor acceleration. I turn the ignition off and then turn it on and the car ran perfect for another 5 miles or so and the problem repeated.

I took it to the Porsche specialist, and he has done the following:

1) Cleaned Spark Plugs (even though it has been 200 miles only since i got a major service)

2) Cleaned Ignition Coil.

3) He has removed all the fuel injectors and says will clean them tomorrow.

4) He says after that he will check the wires to the Engine Control Unit.

He says if after all this, if the "Check Engine" does not go off then we will have to replace the Engine Control Unit.

This is the error code he gave me:

1330 - Misfire in Cylinder 6

Can anyone tell me what the possible problem is? TO me it seems that the workshop has never faced a similar problem earlier and is a little unsure about what has to be done.

Had this same thing on a friends car and was just a poor connection for the coil pack.... happened shortly after the spark plugs got replaced as well. Hope this helps.

I had the same issue in my daily driver (2000 Acura 3.2TL). It ending up being a bad coil ignition. After replacement, everything was fine. Loren is correct in all the possible items.

I was able to identify my problem by exchanging plugs with another cyliner. Same cylinder mis-fire code popped up. Then I exchanged coils and voila the code followed to the next cylinder. If code did not follow, then I would have checked wiring - then injectors.
