Hey guys, I recently put a h22a4 in my 93 civic cx. Just got it on the road and I been working out some kinks. But just today a slight mis occured, and happenes for seconds then idle fine. Went down the road pulled fine and idles fine when stopped. Went out for lunch and at the drive thru the car again at idle missed but for a bit longer and I reved it up and it went away. So just about an hour ago it did it again at the gas station and went away. I kinda have ideas where to start but wanna hear input from you guys. My h22 has had these recent things done to it.......
Timing belt done. Triple checked it
Ignition timing, 16btdc
Valve adjustment
Egr delete.

I dont believe there is a vac leak but will check soon. May be cam position in the distributor? And ya I am running a jdm h22a distributor. Ignition coil has been replaced.

I am also running NGK iriduim plugs could that be an issue due to the fact the call for a double platinum?
