04 camery miss fire only 2 and 3 cyl under load
 

first time post here and i have a real head scratcher......code showing #2 #3 miss fire....no other codes. changed out the typical things plugs, coils and checked injedtors all good. I didi have a blown head gasket between 2 and 3 so i figured that was it.... nope all back together starts right up idles beautiful, but as soon as i drive it ,get up to just about to shift in to 2nd grear..(automatic) it stumbles and then it gets better so it seems around the 2400 rpm mark UNDER a load is when it happens no other time..... PLEASE HELP

all fixed ended up being the ignition coils on #2#3 thought i checked those....guesss not
