What does it mean\"misfire on cylinder 6\"?

I recently got a JB4 and on map 2 I noticed that in moderate acceleration I got a vibration/slight stutter b/w 2k-3k RPM, then it\'s gone.
Found out I have several codes but the big ones would be 29D2- misfire on cylinder 6. Is this a injector problem?
Also got I believe 2AAF -fuel pump plausibility. What does this mean?
If I go back to Map 0, there is no vibration at 2k-3k rpm (I have Dinan stage 2)
Can you guys direct me to what I should fix?

it means you probably need new spark plugs

Either cylinder 6 needs either spark plug, injector or coil. It's one of them. First do the spark plug then if it still happens troubleshoot the next item and so forth

Swap Coil #6 with another cylinder's coil and see if the problem transfers to a different cylinder. If it does, you need a new coil. This would be the first thing I would do.

he has a 2008 335i- my first thought would be "is the car on the original spark plugs?"

if so, it's well-overdue for new plugs

Thanks guys! I'll start with the plugs. I don't think it has ever been changed.

Mine had this same problem, sometimes others would misfire as well. They found injector 6 "leaking" causing fuel pressures to drop. They replaced 3-6 injectors because 1-2 were already replaced during the recall not too long ago. Now all 6 of mine are the NEW part number; apparently they have upgraded the injectors at some point because the originals caused misfires. Car idles MUCH smoother now. I only have 35k miles on my 2008 but I will be replacing the spark plugs next week because I feel like they probably need it by now (with all of the fuel and misfire problems in the past).
