Ok, so I am not a mechanic but here is what I have done so far: Replaced spark plugs with Iridium, checked all coils(appear to be newer, when unplugged engine sound changes). Removed top of engine plate(not technical term) and cleaned all the gunk out of EGR passages. Still have a misfire, any ideas? Seems to get worse with AC on if that makes any difference. Thanks in advance!!

 

bad gas/injectors would be next if you've truly ruled out the coils. Do you know if they are OEM?

 

I do not know if they are OEM, They don't say Acura or anything so may be aftermarket. When I pull them individually the sound changes so I assume they are ok.

 

Are you getting any CEL codes? If so what are they?

Might be time for a valve adjustment. Other possibility is an intermittent coil.
