Hi all, I am not really new here, just couldnt remember my old account info, what email I used before...
So I just got this car and am getting a Cylinder 2 Misfire under load at high RPMSs.
can drive for days with no CEL if driving conservatively. As soon as you step on it hard, it will trigger the CEL. When the CEL first appears, it seems to turn the injector off or something to that cylinder as you can tell it is missing, as soon as the car turns off and back on, the car runs normal.
I have swapped the coil and plugs from the #2 to other cylinders and the it still #2 triggering the CEL.
This last time it did as I was trying to switch lanes on the freeway from a almost 0mph in to a wide open lane, it triggered #2 and #4,
Ive attached the freeze frame pics from scanner, every other time it has been triggered its looked like the one with just #2, and this morning's it was the the both #2 and #4.
the only common thing on both, and every other time, is the high load (98-99%) and the MAF at 38.6 in.hg
any ideas what it may be?

I have the same issue, a hard acceleration triggers the light and the engine runs rough. I have to pull over, turn the car off, then turn it on again and it runs fine. At first I thought it was crappy gas...but I will try the spark plugs too.
