I recently put in new injectors for 3 and 4 cyl as well as new spark plugs. After this, the motor would misfire once it gets warmed up, but it seems that it is only when I press on the throttle. When this happens, it is usually when half throttle and in the lower rpms (2200-3k) and it would kind of surge and buck, and at the same time, the rpms would be rough. Any ideas? I gapped 3 plugs to .038 and 1 that I was unable to gap correctly, because when I first went to gap it, I was frustrated and put too much force. Could the plugs be the issue or could it be the iacv clogged?
