I'm new to Mazda and their tricks... My engine is misfiring at 2200 RPM in one of it's cylinders and the code simply says misfire it doesn't specify the cylinder or the cause (obviously). If anyone knows what could be the cause of my issue even common fixes, like I said I'm new and don't really know where to start. I was thinking coils or the MAF... I have also head talk of a PCM... I put new plugs in and no change. Any direction is some direction!!
???
:bang
First of all what car is it? Is it MS or MZ?
I'm 99 percent sure it's a 2005 mazda 3 gsQuote:

Is it automatic or manual?
is there a way you can post the code that it shows?
sorry hahah, like i said totally new...Quote:

How did the plugs look when you pulled them out? Did one look different than others?
Does the misfire happen with no engine load when you rev the engine, or only under load.
One option would be to disconnect one ignition coil at a time and see if the engine starts running rougher, the moment there is no change, that will be the problem cylinder. Another would be to bring it to a shop that can hook up a mchine to each ignition coil and monitor them throughout the RPM range.
the plugs looked fine, and the misfire occurs when there is any load put on the engine.Quote:

Just bustin your balls haha, I was there! I'd say try the above tip with removing a coil at a timeQuote:

To me it just seems that if there is no other codes along with misfire that this would a mechanical issue. Am I wrong?
Not necessairly. Pulling a coil pack one at a time helps with narrowing down the cylinder that misfires, that doesn't mean that the coil pack on that cylinder is bad.Quote:

Having exact trouble codes, and I have a feeling that with something like this there might be few codes stored, would help a lot.
Had an ignition coil fail on the work van a few months ago. All that I felt was the van loose power almost all of a sudden on the 401, got to the side of te road and the van was shaking a bit. Turned it off, tried to restart it and got nothing. Didn't see a CEL either I don't believeQuote:

Ignition coil and coil pack is not a same thing, at least to me. Cars (and motorcycles) used to have one ignition coil that was used by all of the spark plugs, now our mazdas have individual coil packs = one coil per spark plug.Quote:

Also I would expect some other codes to be there as well, that's why I was thinking mechanical (or like mentioned something bad fuel).
